Sunday morning at 2:00am on March 12th Daylight savings time (DST) officially began for 2023. Today you are no doubt feeling the loss of an hour of sleep, but what is worse is our internal clock (also known as our circadian rhythm) does not necessarily adjust quickly. Thus, we go to bed an hour before our body feels like it’s time and can’t go to sleep for an hour. Yet our alarm clocks still rings at 6:00am, which to our bodies feels like 5:00am.

NY Times: AI Can Read Mammograms as Good or Better than Radiologists
There is a new artificial intelligence (AI) interface that’s been in the news lately called ChatGPT. ChatGPT is a language-based AI chatbot that can do many things humans can do. Some tasks it can do better than humans can do. A week or so ago I asked Would You See an AI Doctor?, Saying:
Radiologists sometimes use computer-aided detection (CAD) to interpret mammograms as a backup to human interpretation. Using both a radiologist and CAD together increases accuracy.
A few days later The New York Times reported on an ongoing test in Hungary, where AI is being used to assist in reading mammograms.
Inside a dark room at Bács-Kiskun County Hospital outside Budapest, Dr. Éva Ambrózay, a radiologist with more than two decades of experience, peered at a computer monitor showing a patient’s mammogram.

But the stark reality is that they can have only 2 out of the 3.”

Bidenomics
Casey Mulligan in the Wall Street Journal:
I estimate that Mr. Biden’s insurance, regulatory and tax policies as implemented will eventually combine to reduce the nation’s labor income by 5% to 6.5%, with an additional reduction in the long term due to education policies in blue states. In two years under the Biden administration, the labor market is already falling short. Real employee compensation per adult … is 3.3% below the pre-pandemic trend.
I estimate that degrowth policies since 2020 will cumulatively reduce Medicare and Social Security tax revenue by at least $400 billion—and perhaps as much as $900 billion. The tax base will shrink even more if Mr. Biden succeeds in levying higher wealth and business taxes.
I estimate that … remote-learning policies reduced prospective Medicare and Social Security tax revenue by $118 billion in present value.
