Hes associated with the scalzi hugo clique. I.e. he has wrote a bunch of books that won a tonne of prestigous sounding awards and got a whole bunch of fawning media accolades, but in terms of actual readership and fans as opposed to companys that disinterestedly bulk order whatever the top rated book of the month is he is on the level of a mid tier fanfic author at best.He's best known for 'The Adventures of Kavalier and Clay', which is the only work of his I've read. It was lauded so heavily I was expecting a lot, but it was one of the worst books I had read up until that point (later displaced by 'A Million Little Pieces' as my lowest of the lows, then later displaced by anything by Frederik Pohl). Maybe his other novels are better.
Given how this clique's main MO these days is to try and "game" social media and the critics by simultaneously engaging in empty "LOOK AT HOW STUNNINGLY BRAVE WE ARE FOR PUTTING ETHNIC PEOPLE AND WAMMEN IN OUR WORK FOR THE FIRST TIME IN HISTORY!" tier wokebaiting while also declaring all possible critics and anyone who might dislike anything they shit out to be ultra evil nazincel terrorists enraged at their courage at showing that ethnic people and wammen exist as to harvest mass positive coverage and to premptively silence any non anonymous critic, It makes perfect sense that this is what nu-trek has been going with in order to try and shame people into consooming enough to break even
