@nntaleb As someone who lives in California this is not like Covid masks where only statistics will tell you that the mask works (it does). With the AQI as it is in NYC you can physically feel that it works.
@pkedrosky I do all comments on assignments that I grade these days using Apple’s speech to text. Kind of learn to live with the deficiencies. I like it so much more than typing. I give better answers in much faster time.
