Like high frequency trading players front-running trades, faking liquidity, manipulating prices, and changing infrastructure to benefit them to really screw people that want to buy or sell stocks? Never heard of anyone getting prosecuted by the legal system for that (besides for taking HFT code with them, but never for screwing a normal buyer or seller).

It would be great if there was more moral in finance, but I think that's wishful thinking and doesn't really distinguish traditional finance or Defi. The only nice thing about Defi is that everyone can see what's going on in contrast to what happens when you do something in traditional finance.
It's only marketing. There is no integrated assistant. It's a plain old button that can be used to activate one of these useless voice assistants on your phone because some people like it. If you're like me, you can use it as an extra control to modify noise cancellation.
It's really about planning. Modern Swiss towns mostly consist of high density buildings with parking underground and most of the areas around the buildings are for walking & biking. The really good thing about high density is that it allows for much more efficient public transport which reduces the need for cars.
Teach them QWERTY. I use Programmer's Dvorak and I love it. But I also have a very specialized setup and everything optimized for myself. Your kids will have to work with different setups in the next decade or two. For them it's more important to be flexible. Later when they specialized themselves and only work in an environment they control they can switch and choose whatever fits them.
