Computing will never be finished like spoons in the software realm because software is like prose. It's a language where we write down our needs, wants, and desires, and instructions to obtain them, and those are always shifting.

I could definitely see standard classical computer hardware becoming a commodity though.

There will also be room for horizontal expansion for a LONG time. If costs drop through the floor then we could see desktops and servers with hundreds or thousands of 1nm cores.
