We'll get more incremental updates and nice features:
* more context size
* less hallucinations
* more prompt control (or the illusion of)
But we won't get AGI this way.
From the very beginning LLMs were shown to be incapable of synthesising new ideas. They don't sit there and think; they can only connect dots within a paradigm that we give them. You may give me examples of AI discovering new medicines and math proofs as a counter-argument but I see that as re-enforcing the above.
Paired with data and computional scaling issues, I just don't see it happening. They will remain a useful tool, but won't become AGI.
And whether they stay affordable is a question of time; all the big players are burning mountains of cash just to edge out the competition in terms of adoption.
Is there a level of adoption that can justify the current costs to run these things?
