+1 Close! It's almost the same with biological neural networks and quantum computers. Our programming paradigms used at present are simply insufficient for operating those kinds of CPUs efficiently. |

Oh yes, that is one more reason to add this to Linux roadmap, this should definitely stay open |
+1 On add it to the roadmap. Or we may as well shut GitHub down. |
That would be great! |
Lol. |
+1 But also add "
|
+1 but recommend "distributed computation of solution to Heat Death of the Universe as
background process" and "closed time-like loop computation for
instantaneous computing." We will need drivers for the anti-telephone processor.

@shayneoAtNorwood @Manglano why not Lol, maybe 100 years in future we could have a working prototype :) On a sidenote, we already have a prototype quantum computer, I think Google and IBM were already researching into that. We dont wanna see Linux die out in quantum computing. Well, only M$hit dreams it. |
