The Great Filter – Are We Almost Past It? (1998)
Combining standard stories of biologists, astronomers, physicists, and social scientists would lead us to expect a much smaller filter than we observe. Thus one of these stories must be wrong. To find out who is wrong, and to inform our choices, we should study and reconsider all these areas. For example, we should…

The pace of major breakthroughs has declined
One of the prevailing narratives of our time is that we are innovating our way into the future at break-neck speed. It’s just dizzying how quickly the world around us is changing. Technology is this juggernaut that gets ever bigger, ever faster, and all we need to do is hold on for the wild ride into the infinitely…

Patriarch of Pandemics
In the last article we covered some of the historical pandemics that rocked the world - smallpox, typhoid, and the bubonic plague. We ended on a hopeful note - many of the pandemics that plagued the world in the past have faded, and that modern pandemics have been far less fatal than historical o

Silent speech with ultrasound
We trained a model to predict speech from ultrasound video of the tongue, no speaking required. It reads open text, generalizes across people, and reaches a 15.6% word error rate on open-vocabulary speech.

Training immune cells to remove ‘trash’ helps resolve lung inflammation
Inflammation is a standard part of our bodies’ immune system response. But sometimes this response becomes hyperactivated in our lungs, causing inflammation to continue unchecked, which can be fatal. Many deaths from COVID-19 have been due to excessive inflammation, which results in acute lung injury.
