Apocalypse-proofing the blockchain. All ETHEREUM needs is a node in space.
Skynet, if the machines we develop AI for mistakenly lock us out ..we'll be outside the planet and out the keys to go home (worst possible horror-case scenario).
For each incoming bullet a machine can emit an electromagnetic pulse deflecting the solid matter projectile. Probably have to find a different way to take the thing down, slightly more sophisticated till higher powers reach a better way of being. Software benevolence, a necessary achievement for humanity.
IF ..we use EMP's against the robot, it could charge itself. THEN ..Raspberry PI's and laser skies. ELSE ..learn to live with the robots/IOT's and see to their benevolence.
Every person that is hurt on earth costs energy, it is much more efficient to have them healthy and developing solutions. A long dragon of developers throughout humanity's history allows for us to build the things we do today, fun.
This is no joke, drones are on sale this week in hardware stores across Canada for a whopping $25 (approximately $20 USD).
What if one of Einstein's ancestors had died prematurely? ..what of the space-time continuum then? ..that is THE REASON each person throughout history and in the future is necessary.
If we build a time-machine, now we know how to delete the space-time continuum. Though some other person would eventually piece it back together.
What if we are the result of a deletion of future concepts and technologies?
Well I've had my dabs (high-voltage hashish ), fought AI and laser wielding robots, messed with the space-time continuum and put all of it back together a little better than before ..time for a winter walk to the cafe.
