Also been programming since the early 80s and I do by far most programming in my head and on paper (I ‘just have to type it in’; that is mostly bullshit because of the real world vs my abstractions but it does save me a lot of wasted time behind a computer).

Screwing the employer is a tad harsh but I am the employer often and I see people coming up with these things, so I give them some room to play. Usually they just go back to the old ways when they see it is not that silver bullet the Medium article claimed. I just can imagine when someone does this with more power or less supervision within a company as an employee and actually costing the company money for some unproven and resume driven thing which does not necessarily bring any business value.
