Is there any evidence at all that would convince you that they're trying to mitigate real risks that actually exist?

What real risks? Genuinely.

I've read all the sci fi they have. It's not hard to see where the ideas came from.

What's being questioned is this sentiment of "The only way to save humanity is for me and my lighthaven groupies to become Xillionaire god-kings"

Is there any evidence at all that would convince you they're just blowing smoke up our asses in pursuit of money?

I mean, we're talking about an administration that has already over-reached in regulating this specific company out of personal bias; is openly seeking leverage over companies for favoritism and graft; hires on the basis of loyalty to whims of a narcissist; makes fun of the whole idea of competent government based on expertise; provides a range of conflicting explanations for whatever it chooses to do; and has been unable to field a team capable of understanding or explaining whatever real risks are here.

Your question is like asking what evidence would convince us that a bag of rocks doesn't have rocks in it. Easy, just take the rocks out.
