Not sure about attorneys, but there are certainly legislators / regulators who think that, or who at least think that every problem they throw at engineers, like implementing end-to-end encryption that their government can backdoor but foreign governments can't, is instantly and easily solvable.
The phenomenon discussed here has engineers believe they can practice law and medicine themselves. So they're not asking lawyers to get them out of a murder caught on national television, or doctors to cure their cancer in three days. They think they can do these themselves.
This is, of course, one of the most important skills anybody can have, but most people are terrible at it (whether by lack of talent or lack of practice) so our society pays lawyers to do it for them.
