Doing it for laughs? Where did I write that? Listen to Musk say "this will blow your mind." It never happened during the presentation, unless pigs with implants excites you. Until human trials actually start, and the [hopefully] more complex human mind is engaged, there's nothing now.
The example I gave about a person walking by the use of electrodes attached to the skin was very straightforward. The electrodes fired to tense and relax muscles in the legs at specific times and in a specific order. This was a preprogrammed operation.
Spending money? Yes, of course. I'm looking for all of the promised developments getting completed. Eyesight for the blind was briefly touched on by one member of the technical team but it involved the building of a megapixel camera into a human eye, or a substitute. And so far as I know, something like that does not exist. It would seem the spinal break connector would be a relatively easy job for the device, but no idea when that connector might be built.
I know a little about investors and inventions. Even with lots of money, no one has set a date for Return On Investment. I'll watch this. But I'll only look more after "First human trial of severed spinal cord connector completed" appears. As one example.
