I mean, "the pieces were already there" is true of everything? Einstein was synthesizing existing math and existing data is your point right?

But the whole question is whether or not something can do that synthesis!

And the "anyone who read all the right papers" thing - nobody actually reads all the papers. That's the bottleneck. LLMs don't have it. They will continue to not have it. Humans will continue to not be able to read faster than LLMs.

Even me, using a speech synthesizer at ~700 WPM.
