OK, so, we're scientists...and we're in the middle of a pandemic...amplifying/arguing over a graph showing a steep decline in job listing...that doesn't control for the pandemic...or even include a line for "overall job loss"...
yeah looks like at the least you might have lines for "overall CS based jobs" and "overall tech industry" and see the same sort of fall off appears. While not all that scientific either logically if you see similaries you can cast some more doubt/support on the hypothesis that ML is special and failing. How is it doing relative to other "hyped" or even just plain technical hiring/firing trends.

Looks like all job postings "collapsed during the pandemic"
