I'm sorry, I do have to disagree. It's little more than recognizing a problem and envisioning a solution. Ideas are cheap.

And in that sense they are little more than entrepreneurs with grand long term visions that require no commitment. Give credit to those who put blood and sweat behind their visions - and make them happen, not make vague 'predictions'. That's what Hollywood is for.

I predict in the future we will be creating food from carbon scrubbed from atmosphere.

I predict in the future that humans will communicate with machines through quantum teleportation via implants

I predicate that in the future that if these predictions don't hold true, no one I know will be around to call me on it.
