Human extinction! Don't panic; think about it like a philosopher.
Most people think human extinction would be bad. These people aren't philosophers.
- A new opinion piece in The New York Times argues that humanity is so horrible to other forms of life that our extinction wouldn't be all that bad, morally speaking.
- The author, Dr. Todd May, is a philosopher who is known for advising the writers of The Good Place.
- The idea of human extinction is a big one, with lots of disagreement on its moral value.
Humans could go extinct. The idea has been floating around science fiction since 1826, it dominated diplomatic thinking during the Cold War, and it fills the existentially inclined with dread. We've had some difficult times in the past, but today the only real threat to humanity is suicide.
While most people would think humans going extinct would be an obviously bad thing, these people aren't philosophers. This strange breed of human looks at the problem from many perspectives and often comes to conclusions that might shock you.
A tragedy, but not a bad thing.
Knowing how confusing that sentence was, he explains the idea by looking to tragic heroes in literature. Characters like Oedipus and King Lear do bad things yet invoke our sympathy. The idea is that humanity is doing bad things that could only be stopped with the extinction of humanity, but that we still have every reason to feel sympathetic for humanity despite this.
The "bad things" Dr. May refers to in this case are the suffering we cause to animals and the damage we cause to the environment. He makes specific reference to the vast numbers of animals we breed into existence, cram into factory farms to live unpleasant lives getting fat, then eat them, as one example. He mentions how human-caused climate change will alter Yellowstone National Park as another. Our often wanton destruction of the environment is unmatched by any other creature.
"It may well be, then, that the extinction of humanity would make the world better off and yet would be a tragedy. I don't want to say this for sure, since the issue is quite complex. But it certainly seems a live possibility, and that by itself disturbs me."
Is this opinion popular? Should I be concerned?
The idea that it would be for the best if humanity died off is held by more people than you might imagine. The Voluntary Human Extinction Movement (yes, it is real) encourages its supporters to not have children in hopes that humanity will peacefully die off.
The perpetually depressed Schopenhauer was an anti-natalist, one who thinks having children is morally wrong, because he thought most people would be doomed to live lives dominated by suffering. Several other thinkers, most notably David Benatar, agree with him. If these arguments were carried to their logical extreme, there wouldn't be any humans left after a few decades.
Others, including Benatar and the extinction movement people, agree with Dr. May that creating more humans causes more environmental trouble than is morally justifiable and that we should stop reproducing now.
Now, none of these groups or people advocate suicide or murder. They argue only that we shouldn't create more people. There is a, generally accepted, moral difference between people who are alive and people who could exist. While saying we shouldn't have more kids doesn't cause harm, since people who never existed can't be harmed, killing people currently alive does harm people. So you needn't worry about armies of philosophical Unabombers cropping up anytime soon.
What about the side for human life? Who is on that side?
Dr. May does refer to stances one could take that would cause you to disagree with them. One such position would be to assume there is a "profound moral gap" between animals and humans. If you did this, the suffering we cause animals to feel could be dismissed off hand because the animals have no moral standing.
Plenty of philosophers have argued for this exact thing. Most famous among them was Immanuel Kant, who argued that we should be kind to animals as practice for being nice to people but considered them things without moral rights. He would probably find the idea that we should drive ourselves to extinction for the sake of those animals to be absurd. Christine Korsgaard, a modern Kantian theorist, disagrees and argues that animals are worthy of some moral consideration while admitting that our capacity for reflective, normative thinking is a unique feature that may have moral weight.There is also a more moderate route other thinkers take. Dr. Temple Grandin, a professor of animal science at Colorado State University and noted autism spokesperson, argues that raising animals for the sole purpose of eating them is ethical but that we should assure them a decent life with a minimum of pain. Her stance would both allow humans to continue existing and using animals for our benefit while improving life for those animals; no extinctions required.
Even Peter Singer, a philosopher who has been known to stake out a controversial stance now and then, argues that we should give animals moral consideration but has yet to say that we ought to die off for their sake. Instead, he has argued that we ought to stop needlessly causing them harm and perhaps take up vegetarianism.
Would the world be better off without humanity?
It is also possible to take issue with the claim that the environment would be that much better off without humans or that the effect of humanity on the environment is so awful that we ought to die off. Nature can be sickeningly cruel without any human intervention. Animals can cause as much deforestation and environmental degradation as humanity does at the local scale. Plants, as well as humans, have caused climate catastrophes by changing the composition of the atmosphere.
There were two dozen mass extinction events before the evolution of modern humans. One of these, the Permian–Triassic extinction event, saw 96% of all marine and 70% of all land-dwelling vertebrate life die. The famous Cretaceous extinction event featured the death of the dinosaurs and almost every land animal that weighed more than 55 pounds as the result of a giant asteroid hitting the earth, as they often have done and will do again. Humans have yet to do anything with nearly the kind of impact on the environment as these random events had.
While our destroying the environment is not made acceptable by the fact a random occurrence might do the same thing, it does make the argument that humans should die off for the sake of the environment lose a bit of its punch. After all, if another mass extinction event is inevitable, which many people think is the case, then getting rid of humans doesn't actually accomplish much in the way of protecting the environment over the long run.
It would only serve to assure that, after that next cataclysm, both the environment and human-made wonders like the works of Shakespeare are obliterated. Since Dr. May does suggest that the works of art humanity creates have value and that there is something to be said for our being the only animal that can truly contemplate beauty, a world where we are gone and nature takes it course seems to be the worst one of all.
The COVID-19 pandemic is making health disparities in the United States crystal clear. It is a clarion call for health care systems to double their efforts in vulnerable communities.
- The COVID-19 pandemic has exacerbated America's health disparities, widening the divide between the haves and have nots.
- Studies show disparities in wealth, race, and online access have disproportionately harmed underserved U.S. communities during the pandemic.
- To begin curing this social aliment, health systems like Northwell Health are establishing relationships of trust in these communities so that the post-COVID world looks different than the pre-COVID one.
COVID-19 deepens U.S. health disparities<p>Communities on the pernicious side of America's health disparities have their unique histories, environments, and social structures. They are spread across the United States, but they all have one thing in common.</p><p>"There is one common divide in American communities, and that is poverty," said <a href="https://www.northwell.edu/about/leadership/debbie-salas-lopez" target="_blank">Debbie Salas-Lopez, MD, MPH</a>, senior vice president of community and population health at Northwell Health. "That is the undercurrent that manifests poor health, poor health outcomes, or poor health prognoses for future wellbeing."</p><p>Social determinants have far-reaching effects on health, and poor communities have unfavorable social determinants. To pick one of many examples, <a href="https://www.npr.org/2020/09/27/913612554/a-crisis-within-a-crisis-food-insecurity-and-covid-19" target="_blank" rel="noopener noreferrer">food insecurity</a> reduces access to quality food, leading to poor health and communal endemics of chronic medical conditions. The U.S. Centers for Disease Control and Prevention has identified some of these conditions, such as obesity and Type 2 diabetes, as increasing the risk of developing a severe case of coronavirus.</p><p>The pandemic didn't create poverty or food insecurity, but it exacerbated both, and the results have been catastrophic. A study published this summer in the <em><a href="https://link.springer.com/article/10.1007/s11606-020-05971-3" target="_blank">Journal of General Internal Medicine</a></em> suggested that "social factors such as income inequality may explain why some parts of the USA are hit harder by the COVID-19 pandemic than others."</p><p>That's not to say better-off families in the U.S. weren't harmed. A <a href="https://voxeu.org/article/poverty-inequality-and-covid-19-us" target="_blank" rel="noopener noreferrer">paper from the Centre for Economic Policy Research</a> noted that families in counties with a higher median income experienced adjustment costs associated with the pandemic—for example, lowering income-earning interactions to align with social distancing policies. However, the paper found that the costs of social distancing were much greater for poorer families, who cannot easily alter their living circumstances, which often include more individuals living in one home and a reliance on mass transit to reach work and grocery stores. They are also disproportionately represented in essential jobs, such as retail, transportation, and health care, where maintaining physical distance can be all but impossible.</p><p>The paper also cited a positive correlation between higher income inequality and higher rates of coronavirus infection. "Our interpretation is that poorer people are less able to protect themselves, which leads them to different choices—they face a steeper trade-off between their health and their economic welfare in the context of the threats posed by COVID-19," the authors wrote.</p><p>"There are so many pandemics that this pandemic has exacerbated," Dr. Salas-Lopez noted.</p><p>One example is the health-wealth gap. The mental stressors of maintaining a low socioeconomic status, especially in the face of extreme affluence, can have a physically degrading impact on health. <a href="https://www.scientificamerican.com/index.cfm/_api/render/file/?method=inline&fileID=123ECD96-EF81-46F6-983D2AE9A45FA354" target="_blank" rel="noopener noreferrer">Writing on this gap</a>, Robert Sapolsky, professor of biology and neurology at Stanford University, notes that socioeconomic stressors can increase blood pressure, reduce insulin response, increase chronic inflammation, and impair the prefrontal cortex and other brain functions through anxiety, depression, and cognitive load. </p><p>"Thus, from the macro level of entire body systems to the micro level of individual chromosomes, poverty finds a way to produce wear and tear," Sapolsky writes. "It is outrageous that if children are born into the wrong family, they will be predisposed toward poor health by the time they start to learn the alphabet."</p>Research on the economic and mental health fallout of COVID-19 is showing two things: That unemployment is hitting <a href="https://www.pewsocialtrends.org/2020/09/24/economic-fallout-from-covid-19-continues-to-hit-lower-income-americans-the-hardest/" target="_blank" rel="noopener noreferrer">low-income and young Americans</a> most during the pandemic, potentially widening the health-wealth gap further; and that the pandemic not only exacerbates mental health stressors, but is doing so at clinically relevant levels. As <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7413844/" target="_blank" rel="noopener noreferrer">the authors of one review</a> wrote, the pandemic's effects on mental health is itself an international public health priority.

Credit: Northwell Health<p>Novel coronavirus may spread and infect indiscriminately, but pre-existing conditions, environmental stressors, and a lack of access to care and resources increase the risk of infection. These social determinants make the pandemic more dangerous, and erode communities' and families' abilities to heal from health crises that pre-date the pandemic.</p><p>How do we eliminate these divides? Dr. Salas-Lopez says the first step is recognition. "We have to open our eyes to see the suffering around us," she said. "Northwell has not shied away from that."</p><p>"We are steadfast in improving health outcomes for our vulnerable and underrepresented communities that have suffered because of the prevalence of chronic disease, a problem that led to the disproportionately higher death rate among African-Americans and Latinos during the COVID-19 pandemic," said Michael Dowling, Northwell's president and CEO. "We are committed to using every tool at our disposal—as a provider of health care, employer, purchaser and investor—to combat disparities and ensure the <a href="https://www.northwell.edu/education-and-resources/community-engagement/center-for-equity-of-care" target="_blank" rel="noopener noreferrer">equity of care</a> that everyone deserves." </p><p>With the need recognized, Dr. Salas-Lopez calls for health care systems to travel upstream and be proactive in those hard-hit communities. This requires health care systems to play a strong role, but not a unilateral one. They must build <a href="https://www.northwell.edu/news/insights/faith-based-leaders-are-the-key-to-improving-community-health" target="_blank" rel="noopener noreferrer">partnerships with leaders in those communities</a> and utilize those to ensure relationships last beyond the current crisis. </p><p>"We must meet with community leaders and talk to them to get their perspective on what they believe the community needs are and should be for the future. Together, we can co-create a plan to measurably improve [community] health and also to be ready for whatever comes next," she said.</p><p>Northwell has built relationships with local faith-based and community organizations in underserved communities of color. Those partnerships enabled Northwell to test more than 65,000 people across the metro New York region. The health system also offered education on coronavirus and precautions to curb its spread.</p><p>These initiatives began the process of building trust—trust that Northwell has counted on to return to these communities to administer flu vaccines to prepare for what experts fear may be a difficult flu season.</p><p>While Northwell has begun building bridges across the divides of the New York area, much will still need to be done to cure U.S. health care overall. There is hope that the COVID pandemic will awaken us to the deep disparities in the US.</p><p>"COVID has changed our world. We have to seize this opportunity, this pandemic, this crisis to do better," Dr. Salas-Lopez said. "Provide better care. Provide better health. Be better partners. Be better community citizens. And treat each other with respect and dignity.</p><p>"We need to find ways to unify this country because we're all human beings. We're all created equal, and we believe that health is one of those important rights."</p>
What’s Eminem doing in Missouri? Kanye West in Georgia? And Wiz Khalifa in, of all places, North Dakota?
This is a mysterious map. Obviously about music, or more precisely musicians. But what’s Eminem doing in Missouri? Kanye West in Georgia? And Wiz Khalifa in, of all places, North Dakota? None of these musicians are from those states! Everyone knows that! Is this map that stupid, or just looking for a fight? Let’s pause a moment and consider our attention spans, shrinking faster than polar ice caps.
Researchers make the case for "deep evidential regression."
- MIT researchers claim that deep learning neural networks need better uncertainty analysis to reduce errors.
- "Deep evidential regression" reduces uncertainty after only one pass on a network, greatly reducing time and memory.
- This could help mitigate problems in medical diagnoses, autonomous driving, and much more.

Amini and colleagues wanted to produce a model that could better detect patterns in giant data sets. They named their solution "deep evidential regression."</p><p>Sorting through billions of parameters is no easy task. Amini's model utilizes uncertainly analysis—learning how much error exists within a model and supplying missing data. This approach in deep learning isn't novel, though it often takes a lot of time and memory. Deep evidential regression estimates uncertainty after only one run of the neural network. According to the team, they can assess uncertainty in both input data <em>and</em> the final decision, after which they can either address the neural network or recognize noise in the input data.</p><p>In real-world terms, this is the difference between trusting an initial medical diagnosis or seeking a second opinion. By arming AI with a built-in detection system for uncertainty, a new level of honesty with data is reached—in this model, with pixels. During a test run, the neural network was given novel images; it was able to detect changes imperceptible to the human eye. Ramini believes this technology can also be used to pinpoint <a href="https://www.theguardian.com/technology/2020/jan/13/what-are-deepfakes-and-how-can-you-spot-them" target="_blank">deepfakes</a>, a serious problem we must begin to grapple with.</p><p>Any field that uses machine learning will have to factor in uncertainty awareness, be it medicine, cars, or otherwise. As Amini says, </p><p style="margin-left: 20px;">"Any user of the method, whether it's a doctor or a person in the passenger seat of a vehicle, needs to be aware of any risk or uncertainty associated with that decision."</p><p>We might not have to worry about alien robots turning on us (yet), but we should be concerned with that new feature we just downloaded into our electric car. There will be many other issues to face with the emergence of AI in our world—and workforce.

Can passenger airships make a triumphantly 'green' comeback?
Large airships were too sensitive to wind gusts and too sluggish to win against aeroplanes. But today, they have a chance to make a spectacular return.
Vegans and vegetarians often have nutrient deficiencies and lower BMI, which can increase the risk of fractures.
