I’m of the opinion that everything that can be invented has now been invented.
Maintenance, support, and derived technology is the wave of the future.
The next generation of would be inventors has no clue. The next really big thing as far in the future.
Ummmmm......I would take some issue with that....
All you need to do, (it's still early) is look at the past. If you do, you will see the most obvious moves done by the largest firms, Microsoft, Google, and Apple and you can make a observation..
All of them, over the past ten years, have exhausted large amounts of investment capital into one or more particular venues...and the two big ones are entertainment and in Googles case, transportation. IMO, VR will be one of the next big things, and of course the automated transport devices. There is a understated reason why MS got into gaming some time ago, and as for Apple, they are so secretive that it's difficult to say what they are pouring cash into right now but one can speculate that they will be directly involved in one or more of the two things I mentioned. Apple likes to come in late....so....(contrary to the aficionado version that claims they are at the forefront) I think it's worthwhile to keep a eye on the Chinese R&D and some of the small unlisted startups in the US and Europe.
IMO, It's clear to me that VR will become the new consumer cocaine for a variety of different needs that they don't yet know that they need to have..
