I liked Dr. Stone and Madoka Magica. The first one is pretty good at being entertainment that also occasionally happens to teach you about practical science concepts and the impacts of new technology, and the latter thinking about what we value and why.
Overlord makes me think about AI a lot. Having a bunch of undead soldiers that can do stuff like farm 24/7 without getting tired or needing to eat is kind of like having robots that can automate work. It also completely unbalances the world economy. And having a bunch of powerful servants who were created to be loyal but don't know their master's goals leads to a lot of unexpected and sometimes pretty bad situations for people. As well as the fear that they might defect if they do learn the goals and disagree.
A lot of people like Serial Experiments Lain but it kind of went over my head when I watched it back in the day. Maybe I'll give it another try.
I just answered a similar question on another post before realizing the post was over a year old and pretty quiet. But yeah, the main takeaway is that I second Dr. Stone, I've written about its connection to EA a couple times at this point, and while it's not my favorite piece of science fiction, or even probably my favorite anime, I think it is a good fun show that's unusually relevant to EA.
