Are you not concerned that you, too, will go away?

Feels like everyone should be on one hand. On the other hand it also feels like a massive recalibration of what companies can/should do. They spend massive amounts of money on AWS, Datadog, GitHub, CircleCi, et al. If it becomes easier to host/roll your own it's a big increase in the demand for engineers.

Ultimately software is everything these days and the economics make the demand insatiable. We've gone through many cycles of "X" but on computers/web/mobile. There's going to be a massive amount of "X" but with AI companies that will need engineers.

Or at least this is what I tell myself to sleep at night.

If I don't stay ahead of the curve, yes. But I can't stop that development. What I can do is leverage the technology enough to be more valuable than those who don't. By e.g. knowing how to set up processes like the above.

Ultimately, we'll need UBI or large scale cuts in working hours or similar if AI progresses to the point of mass unemployment - the alternative would be massive social unrest. In the meantime I expect to keep doing better than average.
