I guess hubris is the only explanation.

It sounded like everything to do with this company was defying sound engineering to save money and call it innovation.
Making a wound carbon fiber hull and then putting titanium around it is all about saving costs and saving weight for transport. He completely failed to understand that carbon fiber is used for pressure vessels (like a bottle holding gas) to be strong against something pushing out from the inside but not crushed in the direction as carbon fiber is strong in tension but weak in compression.
In it end it's like you took a bunch of string and wrapped it around a spool and poured expoxy glue into it. It's going to be widely uneven and all the stresses would be invisible until the whole thing delaminated into a bunch of fibrous strings.
