I mean, he'll probably be okay. Deep sea submersible technology is pretty nailed down at this point.
What happened with the Titan is the Ocean Gate guy thought he was smarter than everyone else and could make a deep sea submersible with non-standard components (carbon fiber that had passed it's expiration date, off-the-shelf electronics, oh and a window not rated for the depths it was going). And to be fair the out of the 15 attempted dives down to the Titanic only one of them catastrophically failed. A 6.6% failure rate isn't too bad... for some applications.
Suuurree they are. Hasn't chromium getting more expensive over the past couple years? I'm guessing this sudden concern about the environment and the health of the workers will save them quite a bit of money in the long term.
Still, credit where credit is due, at least this cost cutting measure that actually has positive benefits for once.
