I read this when I was a pre-teen because my grandmother's brother gave me a compilation of asimov stories named '9 Tomorrows' and this story is one of them.
The whole book really blew my mind!

I can't explain it exactly, but somehow being written over 60+ years ago adds this other layer where you have this funny feeling of looking into the past to see the future.
The story was written after the invention of the transistor, but it seems Asimov hadn't heard of them or didn't grasp the implications, and assumed that computers would be based on tubes (or valves, the word used in the story) for billions of years into the future (but eventually they would be "molecular valves" and a powerful computer could be only half the size of a spaceship).
That was a wonderful story but has a somehow unsatisfactory conclusion to the question. Spoilers below
SPOILER
The story appears to assert that to be human you need to have the imperfect faculties of a human body, but I would say that Frost started becoming human upon his creation which gave him curiosity
Oh man, Asimov was so bad with futuristic ideas. If you'd like to read good thoughts about future, go for Stanislaw Lem (Summa Technologiae, Golem XIV)
