Was just reading another thread about Elon saying, "The more I learn, the worse it gets." Everyone is hoping he will reveal all.

My question is, does he really know or have access, to everything? Couldn't all those who left (and there were many) have taken or deleted or destroyed a lot of the evidence of what was going on there?

Btw, I started this thread because the other already had so many replies and I thought nobody would see my question. I know many people here aren't technologically proficient, so it would be reassuring to hear that he can get his hands on the info. Thanks.
