I think generations are valid, but the demarcations for the generations are terrible. They should be based on watershed moments in history of a given country. Since different countries will have different watershed moments, generations should be country specific. For example, a "boomer Iraqi" makes no sense because Iraq didn't have a baby boom equivalent.

In terms of zoomers, I demarcate the two watershed moments as 9/11 and Covid. In other words, zoomers weren't old enough to remember a pre-9/11 world but old enough to remember a pre-Covid world. Since someone born a day before 9/11 would have zero memory of 9/11, let along a pre-9/11 world, there can be a ~4 year offset before the actual year of the watershed. For me anyways, a zoomer is someone born between 1997 (2001-4) and 2016 (2020-4). Within this almost 20 year range, you could subdivide this so you can categories like "old zoomer" or "peak zoomer." The 2008 financial crash and the 2016 presidential election are two minor watershed moments. So 1997-2004 are the early zoomers, 2004-2012 are the peak zoomers, and 2012-2016 are the later zoomers. Agewise, this is 19-26 for older zoomers, 11-19 for the middle zoomers, and 7-11 for the younger zoomers.

The hate of skibidi toilet is just older zoomers cringing at younger zoomers, but everyone involved is a zoomer.

The split should be between pre-Covid and "post"-Covid, so your oldest alpha is like 7. And this is only partially effective because society has collectively decided to pretend Covid didn't happen, so it's not a very significant demarcation.
