The whole concept is really cool!
Although I personally would rather achieve that without the suit…
(hello, BCI!)
There’s just one thing you seem to keep forgetting:
Just like a new brand of smartphone, or a new operating system…
You need apps to use on it, or it will have no use.
Take “piloting a drone” for example…
even right now, I can technically pilot a drone using a keyboard.
But… I need to plug my keyboard to the drone first, right?
But drones don’t have keyboard connectors.
So…
You need to take a drone, and hack it… then make a hardware connector, and then write a software interface for it.
Then you can control it.
But even then, that’s not gonna be universal.
Each different drone/make/model will require a whole new connector and a whole new interface.
It’s sort of a chicken and egg situation
