"don't we all think that ideas are cheap"

No. We don't. Original good ideas are exceedingly rare.

Also, what we really have learned, is that the typical techie isn't interested in pureness of thought and originality, exploration of the beauty of the unknown, but rather making a quick buck.. A good idea will be taken and used without credit.

We'll see whether or not LLMs have original ideas soon I guess. I wonder.
