> I don't think LLMs make what I do irrelevant, but I have thought that I'm going to have to improve how flashy my simulations look to compete better with non-experts who use LLMs.

This scares me more than "LLMs replace humans". You're going to have to take away time from doing the actual work to replace it with doing bullshit work to impress an ever more detached "decision" layer.

I don't even think the posted page qualifies as a "simulation". It's at best an animation with a calculator/model side-by-side.
