I liken the discovery/invention of LLMs to the discovery/invention of the electric motor - it's easy to take things like cars, drills, fans, pumps etc. for granted now, and all of the ergonomics and standards around them seem obvious in this era, but it took quite a while to go from "we can put power in this thing and it spins" to the state we're in today.

For LLMs, we're just about at the stage where we've realized we can jam a sharp thing in the spinny part and use it to cut things. The race is on not only to improve the motors (models) themselves, but to invent ways of holding and manipulating and taking advantage of this fundamental thing that feel so natural that they seem obvious in hindsight.
