Amazon drone delivery comes to mind…

Eh, maybe. I have a less myopic view... I think their Imagineers just like pushing the envelope, and there's a difference between awesome tech vs things that can withstand the wear-and-tear of millions of guests.

Nothing about all that tech makes me think Olaf could withstand a hug from an excited kid.

Disney does a ton of R&D that doesn't directly make it into the parks, such as smokeless fireworks (they donated the patent for this) and their holotile floor (basically an endless VR room you can walk around). I imagine they don't know the practicality at the start, like any good R&D.

Defunctland is genuinely amazing and always a fun watch, and I never regret the time spent on their videos, they're kind of like a special occasion... though they're getting incredibly long... :)

There are a few older shorter videos in the half hour range, I highly recommend checking them out if you find some quiet time! (It's awfully hard for me too in recent times, I haven't gotten around to watch the Living Characters one myself, so I can't give the gist... I'm just glad I got the holidays off to finally catch up!)

The basic gist is that while the tech is cool, it just ends up being impractical for regular use in the parks. (But like the other poster mentioned, with Defunctland it's less about the tldr and more about the journey and fascinating segues he takes)

Totally get it's difficult to make time with kids, but depending on your kids ages... the video shows a LOT of Disney characters talking and doing things and the videos are colorful, so it could work as something you can listen to and they won't mind having play in the background!
