Hardcore developers != A knowledge about the internet/how front end works. I don't think it's even a point to mention at all. I picked up programming 6 years before I got access to the internet, in 2015. Computing has developed so much these days, it's like expecting a Neuro to be your Oncologist. They may know basically how stuff works, but not everything related to a computer.

Sure. It’s just that if developers (just adding these were web devs) don’t know or care then for the common folks this might be completely hopeless.
