That's a really good point the Drinker made re: the lack of life experiences on the part of today's writers. J. R. R. Tolkien and C. S. Lewis were both WW1 veterans who nearly died in the trenches of that war (Tolkien from illness, Lewis from friendly fire), and both went on to have strong scholarly careers in addition to writing with Tolkien, in particular, famously becoming a professor at Oxford. Their works need no introduction and are still internationally beloved, genre-defining modern classics.

Meanwhile let's consider someone like Hugo Award-winning author Becky Chambers. She's got the publishing industry and media outlets like Wired shilling hard for her books, portraying her as a trailblazer of 'hopepunk'. WTF is that? Well, I've seen someone sum it up as 'comfort food for the kind of people who think frosting is a cake', and I can't disagree with that assessment. Chambers herself came from a well-off Californian family, then worked in theater & as a freelance writer before going into writing; she essentially has had, as far as I can tell from her public profiles, no truly dangerous or demanding life experiences (doesn't even have to be wartime experience like Tolkien & Lewis, something like the depression & poverty Rowling struggled with while writing Philosopher's Stone or even having to work in fast food & retail would have qualified) in her 36 years.

And it shows in her works. They're twee, simplistic (to an extent that literal children would get bored of them very quickly), puddle-deep tales populated by characters who universally sound either like bourgeois coastal Californians, or what bourgeois coastal Californians think people from outside their bubble sound like (usually these are villains) - the literary equivalent to High Guardian Spice. I haven't met a soul IRL or online who has bought or heard of Chambers' works despite her friends in the publishing industry trying their best to promote her. They have no lasting cultural impact and never will, hell she'll be lucky if she retains any relevance in 3 years' time.

I suspect the same is true of the nepotistic hacks who have been getting hired into writers' rooms in Hollywood at an especially high pace since the 2008 Writers' Strike. Only Hollywood has a lot more money to play with & isn't quite as moribund an industry as publishing has been since self-publishing became much easier & more popular.
