I don't think it's egotistical, I would love to ask some questions to my great great grandparents, learn more about our family, what things were like for them back then, and more. I assume (and hope) my descendants would be interested in the same one day.

Re: more realistic AI, I don't know if "good" is the word, fun, easier to chat with? I'd love to have a smarter Alexa-like assistant who I can pop up on a screen or jump into where I am and have a chat with, have her pull up information for me, feel like she's really there working with me or helping out around the house. People love the human side of AIs so it's not just a cold interaction, it was always common for people to say "thank you" to alexa and write in saying they thought it was really nice when she would respond for example. I know I personally like that too. Even for video games it would be awesome to have very realistic NPCs you can interact with, keep embodied in the game.
