Seems like this thread will be full of non-sense and jokes for the next 3+ years, about this and that fantasy.

It's a very simple game: you don't need quantum technology, CPU whatevers, nuclear plants.

Puzzle 71 can be solved with around 1 to 2 million $, and the technology already exists, it's called GPU renting.

The only problem is that it makes no sense to spend that amount of money to only get back 700.000 $

That's the ONLY and SUFFICIENT reason for why people like Bram didn't already jump on the 71 wagon.

Trying to solve this with CPUs only increases the costs several times. You people need some reality check about some basic facts about costs of computing power. Solving something with technology that does 100x times less work per the same cost makes no sense whatsoever. It's just a waste of time and energy, no matter what anyone says. Just the same as when you play the lottery, you're most likely not going to win, but lose. Solving something like 71 is the same as winning the lottery every single time, each second, for a lifetime. Think about it before wasting time on this with the wrong (or inexistent) strategy.
