This is only true if it plateaus. What you are saying is “I don’t think LLMs will achieve superintelligence.” Which is a fine opinion to have, but it’s an opinion.
To me it looks like they've been pretty plateaued for a good while already? Sure they do marginally better on benchmarks or whatever, but to me as a user there's really not much difference between chatgpt today and chatgpt a couple years ago. Main difference is just added capabilities like web search, image recognition etc.
For coding you still need to be in control if you want a good result.
In other words, superintelligence often referred to as AGI might either be months away or just VC-Money induced cult-speak many fall victim to.
It doesn’t matter because the only certainty is that it’s not here now, and neither tomorrow etc.
