It is mind-blowing when you have some sort of idea of how complex an endeavor it is to create programming IDEs and UIs, and to see in one document how many man-hours must have gone into them and their iterations over the years.
This is also something that I find very impressive. Everywhere you look, the same thought comes up. All these buildings in the city have been built by someone sometime with so much effort. Then again, I think: maybe not so surprising after all if you consider that 100bn humans have ever lived. That’s a lot of man-hours available there
