What is "BigHead style devs"?
BigHead is a character from Silicon Valley who doesn't actually know how to do anything, does basically zero work, and manages to still fail upwards. This is describing devs that are sitting around and doing an hour of work a day and aren't actually achieving anything but have somehow managed to not get fired for low performance because their manager isn't paying attention.

I think for a lot of people this seems nice on paper, but in the past I've realized that you can be so bored that you actually start doing work.
