This is unironically my favorite kind of HN comment: to say something incredibly rude and/or condescending but wrap it in the right kind of thoughtful language to qualify as HN nice The original punchline ("you don’t learn the actually valuable lessons.") was just a bit too sharp, so you even edited in a psuedo-clarification which actually just repeats that punchline but in a softer way, masterful!
My intention was actually to inspire others to maybe also start preferring long-term/maintenance work, because I feel there’s a lack of enthusiasm for that. Almost invariably after submitting, I see how I could clarify and/or expand on my thoughts, so I often do end up editing.
In my experience separating the roles out is silly if you're an engineer yourself. We do this a lot and that leads to silly mentalities. Greenfield developer vs maintenance engineer, MVP engineer vs Big Tech dev, FOSS hacker vs FOSS maintainer. Each of those dichotomies speaks to cultural differences that we humans amplify for no reason.
In truth the profession needs both and an engineer that can do both is the most effective. The sharpest engineers I've worked with over the years can hack new, greenfield stuff and then go on to maintaining huge projects. Hell Linus Torvalds started out by creating Linux from scratch and now he's a steward of the kernel rather than an author!
