Can you please read the article again? I was advocating for a maximum of two screens, not one. Perhaps you missed that tiny detail somehow.

Unfortunately for you, I have also been an electrician at one point in my life, and no, electricians don't carry 40 screwdrivers, they carry just a couple with interchangeable tips. So your analogy doesn't hold up.

I also never claimed that if you genuinely need three screens you should force yourself to less than that. What I claimed was that 90% don't need three screens and there is plenty data to support that. Maybe go and check out the companies around your city and see what the situation on the ground is for yourself. I have been coding for just over a decade, and two screens were always more than enough regardless of whether it was web, android, iOS, macOS, LAMP stack, MERN stack, etc, so I think I know a thing or two about investing in one's vocation. That's doesn't mean I need to be irresponsible and piss on my environment. Even if that third screen would increase my velocity by 2 days/project at the cost of cutting down a tree, still wouldn't do it. Trees need 100 years to grow, while I've only gained 2 days's worth of time. It's a cost-benefit analysis that extremely few software developers do these days. Energy is taken for granted, sadly, and you don't seem to care much about it either.
