I've used many of these points in talks with no-coiners and new coiners.
I'm kinda curious how people still get to the place where they think the NSA could have a "backdoor" to SHA-256 (no one seems to be able to explain how exactly. I guess if they could, then it would be already a problem haha). I get the chance of quantum computing, sorta. If anyone else has some really good breakdowns on the "backdoor" concerns I would like to see them.
For those wondering how it SHA-256 works Matthew Kratter did a good video on it a while back.
