Most good writers don't hit their stride until their 40s and most Millennials who have succeeded in writing before that are people who are equally nepo-baby and minority.
Lets face it most Boomer writers who were successful in the 70s sucked, most Gen Xers who succeeded in the 90s sucked. Most millennials who are profiting off connections solely suck.
In 20 years all the good writers will be Millennials and we'll be asking why Gen Alpha has no good writers.
