Gen Alpha start must be mid 2010's instead of early decade

why?

Due to the Pew research center, so the preceedor of it ranged 1997-2012. Also 16 years range after baby boomers are make more sense then 15 years.

2012 is tentative not a fixed end they were planning to change it so it's not actually 1997-2012 it's 1997+ but that's outdated. The most accurate range is 2010-2024 because GPT-1 and Transformers were created in late 2017/early 2018 at the peak of 2010 kids' formative years.
