I love how they emphasize that doing a feature well takes a long time. I think this is somrething you can only understand by starting a company. It's really hard to do a feature such that it will workin all the cases in the real world.
Thats not really true. When your working as part of another company there are abstractions around you created by others that protect you.
You dont have to deal with a lot of stuff because a lot has been abstracted away.
In the startup world, either you pay for the abstraction or you deal with the real word.
Lots of people say things like "I could code that in a day" but when its for a startup, that one thing could take a month to do right.
Its completely different when its your own startup. Completely.
