Given musk (with no cave diving experience) called the expert cave diver a pedo when he was told the sub was useless, threw an obviously annoying sign on the roof, started a stupid tunnelling company which would have taken 3 mins of market research to realise won’t work in reality… I hate to think what crap ideas he contributed to the researchers.

The only people who should even remotely consider it, are people who are terminal and who get paid millions by musk
