This sums up my and many others timeline of his understanding of engineering diciplines: https://mastodon.social/@rodhilton/109572674700288958

What engineering? Him doing mediocre PHP code work in the 90s?

He is (inaccurately) known for his engineering _because of_ his marketing.

As I said, he's a marketing genius.

Or maybe "was" is more accurate.

you must not be an engineer.

He doesn't build anything. Everything he's done has been acquisitions that he tries to astroturf as founding.

*financial engineering

See? Great marketing, he is not an engineer.
