QUANTUM SUPREMACY. Google Researchers built a QUANTUM COMPUTER that took 3 minutes 20 seconds to perform a caculation! Why is it a big deal?

Because it would have taken today's computers over 10,000 YEARS to calculate it. Or so they say.

It isn't ready for market yet. That will take several years. Also I have no idea how they would know it would have taken 10,000 years to replicate that. Do you?
