Maybe you are right but I don't think the comparison holds that well. I can't take a scan of myself and send it to some AI because I don't have the hardware. I have to go to some highly consolidated business.
But the last time I did something legal with AI there was no such choke point. It walked me through filing a trade mark and I didn't have to leave my desk.
The difference in capital deployed is huge. A common laptop on my desk vs big bucks for a real estate full of medical imaging equipment. If radiology becomes less profitable the industry won't deploy as many imaging machines. Legal doesn't have that moat.
