A technology may not be literally stabbed, but I think it is fair to say that it very well may get stabbed metaphorically. It may even lead to the complete demise of the technology.

Passionately calling for the death of Next.js isn't really any different than calling for the death of a person, other than you may perceive it as being different if you hold people more dear than technology. But, in that case, that's just your arbitrary opinion that means nothing to anything other than you. There are no doubt some who would be more concerned about the loss of Next.js (bad example; nobody would miss Next.js, but you get the idea) than the loss of a person, which is equally valid. The true arbiter of truth, the universe, certainly doesn't have greater feelings towards one than the other.
