Are we talking about developing modern code on an Apple 2 now? If so I misunderstood the parent post, because they were using the past tense.
In any case, consider this: how do you feel about your current suboptimal, unproductive hardware & software of choice right now? Your current programming language and monitor resolution cannot be used to code. It's simply not possible to be productive with them.
Think I'm exaggerating? Ok. Fast forward a few years and let's talk about this again. Maybe you'll understand my frustration...
Then we agree! I was pushing back against the notion that one cannot be productive unless using a { 5K monitor; three-monitor setup; mechanical keyboard; $YOUR_FAVORITE_TECH_GADGET HERE }. In other words: it's not "time to upgrade your monitor" ;)
