It's the backbone of the entire company I work at. And I work at one of the largest companies in its field. If it went down for an extended period of time the company would grind to a halt. I guess it's called "IBM i" now but everyone calls it AS/400
I am not a programmer, but on 2 occasions I was able to improperly fix (1 argument in 1 line stuff) very small bugs without really understanding how. I've also made a number converter (dec-bin-hex) at least twice. I know those aren't a lot but it's weird that it happened twice twice.
I'd say there's an issue here with language design having major tradeoffs, but maybe it's just a paradox*? Though I have found a language I like (even though I'm not learning it because other issues), so I know it's not impossible at least.
*= Like the people who could make something with less tradeoffs don't have the need/desire to do that, they just use the existing stuff. Though that is much more fitting for visual programming.
