If google finds a way to run itself with 5k developers instead of 30k, that's a scary change
If on the other hand we develop tons of cool hands-on automation technologies that deliver lots of value but require programmer-like people to run them, that may sustain the labor demand for a while
there's an argument gap between 'AI is taking developer jobs unless you can do ML' and 'basic app development, even when non-fancy, is like pulling teeth and requires experts if you don't want to deliver crap that fails all the time'
I think we're still living in the 'basics are hard and require experts' world for 18-36 months and then the tooling fills in and starts to make magic easy
