It's tricky since the future of AI isn't something anyone can really prove / disprove with hard facts. Doomers will say that the rate of improvement will slow down, and anti-doomers will say it won't.
My personal believe is that with enough compute, anything is possible. And our current rate of progress in both compute and LLM improvement has left Doomers with shaky ground to discount the eventuality of an AGI being developed. This just leaves ASI as a true question mark in my mind.
