Why should one believe a 17 year old, working 100 hour weeks and micro-dosing (really, what does this have to do with anything?) knows or is more capable than a 55 year old?
For that matter, I'd be skeptical about what any bank employee says about the SEC lol. My mom had worked at a big bank for decades and is not always saying nice stuff... (But in context it's cus they make her life harder)
While there's probably something to the motivated young weirdo hacker theory (it was William Burroughs who said "only the young bring anything in, and they are not young very long"), I would also very skeptical what a JP Morgan banker has to say about the SEC. It's like asking a bank robber what he thinks of the police (hyperbole, I know. Bear with me). There's a bit of a natural bias there.
That said, JP Morgan has launched their own Ethereum fork and is working closely with the Enterprise Ethereum Alliance and (to my knowledge) Vitalik Buterin. It seems they're sincerely chasing this tech (dragon?) for better intentions or for worse.
