If you work doing ML in production, you know how incredibly difficult it is to get an extra % improvement. The idea of exponential growth that accelerates into the singularity is a sci-fi concept that I have never experienced.

From the outside we've experienced exponential improvements in ML models, sure. But those didn't come out of nowhere. They are powered by massive efforts involving humans.

Personally I'm not worried about losing my dev job to machines in my lifetime.
