Some of the process of expanding the frontier is not parallelizable and is built on top of previous discoveries. And pushing the frontier requires doing things in the real world, or running experiments that take significant real world time that can hurt your 1000x faster claim.
how can you be so sure that AI cant improve to a level where it has original thoughts, Creativity and imagination.
remember that our input is limited to our sensor capability. AI has an unlimited ability to add more sensors and as a consequence collect input that we are not aware of, then whats stopping it training on information we dont have access to?
you cant. no one can. we haven't maxed out this technology or the amount of compute we can throw at it yet. (we may have maxed out the economic viability of it though... I think we'll find out in the next 12-18 months.)
>they can collect their own data with robots...
This is still sci-fi.
