Question why is it so easy today to build reusable rockets? Is it because the onboard cpu speed of the chips can solve more granular control problems with low latency?

Proof of concept. It's a lot easier to do something, if you know it can be done.

I mean, SpaceX also knew it could be done since reusable rocket tests happened in the 90s.

Don't you mean the SpaceShuttle in the 80s? or Delta Clipper which didn't reach orbit?

Really, what SpaceX did was radically different from the tests in the 90s from the rockets, to the controls, to the reusability goals. Otherwise they wouldn't have built Grasshopper.

Now NewGlen is kinda a knockoff of Delta Clipper, but that's a different beast.
