Moreover we haven’t seen all the effects of today’s tech to understand the net benefits.

E.g ‘productivity’ is seemingly increasing but what is the effect on a firms financial position? It’s all speculative and experimental right now.

But saying "LLMs are not good at architecture so software engineering has a bright future" is _also_ extrapolation.

You're probably on point there.
