Don't be confused. He just needs a better copywriter.

Realize that in aerospace etc. this is possible where 9-12 9s of reliability are the common minimum accepted. Communicating this to a field which strives towards 5 9s and is used to charlatans is difficult, and he isn't succeeding. His chosen expressions sound bombastic and conversation ("can't be hacked") compared to the technical equivalents, but developers and engineers outside of this subfield wouldn't fully understand them.

does sound baffling but when backed up by his laurels, we can charitably imagine what he really means - and it's not so difficult either. From the bottom of the barrel, using slightly better algos in python to rewriting it in rust, we can all do this. His company presumably goes further with Ada, formal methods and exotic tooling to get extra performance out of microcontrolers.
