It always amazes me how bad the software world is at keeping lessons learned as learned, especially when compared to say engineering. It's as if every 20 years or so we throw away the books and reinvent it all from first principles, hopefully this time with fewer mistakes overall but usually we end up finding both new ones and re-do some old ones.

It's because software engineering, which deals with bits, evolves dramatically faster than other engineering disciplines, which deal with the physical world.

It’s almost as if we need to write some unit tests. For our profession.

It's almost like "move fast and break things" isn't such a good mantra.
