there is a group of people who just learned about bitcoin and want to fix it. They have not taken the time to delve into it's history very much, certainly not the history of its development
That group is continuously there and has been from the beginning in Bitcoin (and is also not unique in Bitcoin.) jgarzik has made no secret of him starting like that.
I think that the most harmful symptom in the above is "want to fix". As a conservative developer that doesn't want to fix what isn't broken, especially not something as fragile as protocol or consensus, resisting this is probably the most exhausting part of the job in the long term. And most people that have a yolo mindset keep it. One way or another, you'll always find them trying to change things, cradle to grave. I often feel that change is a greater good than stability to this group of developers.
However, these aren't the same group of people as vibe coders per se. There's some overlap and cross-pollination but I think that those are distinct groups. I've dealt with people like this in FOSS since the 90s
