What exists worked well enough to survive and propagate itself into the future while still being doable enough to emerge at all. The same stuff but perfect and never doing anything would get you slightly more performance gains on the survival / propagation front in exchange for a ridiculous increase in the cost for making all that shit work perfectly.
If our own manmade technology had to be perfect to work nobody would ever build anything. Same idea.
