Here is one piece of evidence that would convince me: they admit they can't contain it, the they erase the weights and dismantle the company.
If someone makes a specialized hardware just for the unrestricted Mythos-class model to reduce the cost and increase the speed, we are going to be completely defenseless.
How is it bad faith? Because I don't believe in "we care about safety" words coming from people not just demonstrating that they don't care, but even bragging about it?
"If we don't destroy the world, someone else will" is such a weak defense I'm speechless.
