Reeks of Juicero.

NFS lock and unlock. GPS locator. Capacitance touchscreen controls. Hydraulic disc brakes.

Companion helmet with wirelessly connected brake lights, and noise cancelling(?!) speakers.

Why do we need to learn the same lessons over and over again?

There's literally thousands of e-bikes with touch screens and it would be unsafe for a bike of this weight to have anything other than hydraulic disc brakes, which are the standard for just about anything that isn't a road bike these days. Locator also pretty common even on $1,000 ebikes.

But yes, other stuff seems to be features for the sake of features.

E-bikes with properly adjusted mechanical disc brakes are perfectly safe, and mechanical brakes are easy to adjust yourself without the need to take them to a bike shop. It's the discs that are important -- not whether they are mechanical or hydraulic.

conversely hydraulics don't need adjustment

...except when they do. If you get a leak or an air bubble for example and have to flush the system, you'll need a trip to the bike shop.

If you put miles on your bike and ride hills, you'll spend way more time fiddling with an allen/torx on the inboard pad or the adjustment barrel on the cable as your pads wear. The bleeding procedure for hydraulics is for sure messier, but still very doable in 5 minutes. When you do have air in the system, pumping the lever a bit gives you back some braking function.
