Too gawd damn much! Go back to an Apple II, An Atari 800, A Sinclare ZX80, You turn them on. They execute a few instructions and then are ready to use. Contrast to my linux boxes that are a million times faster but takes ~2 minutes until I can use them.

Yea, I know, things have changed for reasons

Still... It's sad to me how long things take to get started and all of those 100s and 1000s of layer are each full of vulnerabilities waiting to be discovered.
