I don't know, shows from the 90s like Evangelion or Bebop have stood the test of time, and are regarded as masterpieces now, despite inherent flaws to both. Even the 2000s had some great weird shit like Gurren Lagann, Samurai Champloo, FLCL, mushishi, and others. What will people say was the "Bebop" of the 2010s? Kill la Kill? Psycho-pass? MS100? It's all good, but is it great? We're eight years into the 2010s now and what has come out that you think people will still be watching in 30 years?
Seasonal Anime has killed the experimental side of the industry. It's all trying to grab the most eyes as fast as possible, sell as much merch as possible, and then let people move on to get temporarily obsessed by something else, and buy all THAT merch.
