Software engineering in general is pretty famous for unironically being disdainful of anything old while simultaneously reinventing the past. This new wave is nothing new in that regard.

I'm not sure that means the people who do this aren't good engineers, though. If someone rediscovers something in practice rather than through learning theory, does that make them bad at something, or simply inexperienced? I think it's one of the strengths of the profession that there isn't a singular path to reach the height of the field.
