When it comes to changes, I bet that cutting out unnecessary plots, characters, scenes will become an increasingly popular procedure. This has been happening for a long time, but people are increasingly pushing for it. We have less and less time, American rules are increasingly coming into play (I don't know how to put it... So in other words - they give money, so they demand), we as viewers want them ourselves, which can be seen in every aspect of art. We prefer series with 8-10 episodes, books are getting shorter, stories are increasingly focused on showing specific elements, films are increasingly more easily available in conditions convenient for us.
A practical example of such changes - side stories (serving character development, constituting an introduction to the story or something like that) in Netflix anime are increasingly disappearing. If possible, they adapt it or transfer its essence to another scene, and if not, they simply cut it out as unnecessary. This is clearly visible in the end credits - there used to be a lot more voice actors, now there are fewer of them. Likewise, there are fewer cartoonists/people doing simple tasks. Why? Because their job has been taken over by AI.
