Please read more carefully. The "science fiction" applied to your "connecting parallel universes". That's not reality. In fact, there is nothing that suggests such things actually exist, other than in the minds of the great science fiction authors.Terry McCracken wrote:bob wrote:Not being "myopic" at all.

chess won't be solved by 2060. Or even 2160.
This is something that simply is not going to happen. Even a density of one billion times one billion times greater than today's chips won't even come close...
What do you get if you divide 2^160 by 2^8? 2^152.
the math is _daunting".
I thought we were talking real-world scenarios? Not science-fiction...
They may even be able to actually connect to parallel universes and work in tandem, so yes that technology could indeed be used to solve chess.
I'm equally tired of the "this will one day be doable" when it is so obvious it will not be done. We knew checkers would be solved 30 years ago, we just didn't know when. No serious researcher says that chess will be solved by 2060 or at any point in the future. Wonder why that is?
Even Jonathan realizes this!
I'm tired of that can't be done crap...that's what truly is absurd! It holds back scientific and technological progress!
based on what? I bought a 2.8ghz processor 4 years ago. You can almost buy 4.0 ghz today. 4 years, not a factor of two. That's a fact...
You're a computer scientist, but you've but up barriers to things that are so different to your understanding and make false comparisons to the past evolution of computers. Well, the next 50 years will move much faster than the last 50 years. That's a fact!
You have _never_ seen something "impossible" done. Nobody has, for obvious reasons.
I have seen the impossible be done and I'll see it again!
I've seen you post...
Robert, you are not an expert in quantum computing, that is obvious. It will be done, it's not science fiction!
quantum computing exists. In a useless form today. But even if it becomes a reality, you are still going to be dividing a huge number (potential search space) with a small number (quantum computing speedup). You still end up with a huge number (time required to search that space, even if it is searched ridiculously fast.)
