I wonder how one of Google’s data centers compares.

Jokes on you, I put my life savings into GameStop, bought $20k worth of guns, a $85k lifted trucks, and a $500k house while making 50k a year. All I need to do is have a mild medical emergency and I might beat the American Dream speedrun record.

I’ve already alerted the council and they became as hot in the face and angry as a 4090

They still can't find the prime factors of the number 21 with a quantum computer. They're promising, not impressive (yet).

Perpetual motion is fine, perpetual motion you can extract enirgy from isn't. An object in a stable orbit with no drag (hypothetical truly empty space) around another object would never stop or slow down.
A time crystal is a harmonic oscillator that neither loses nor gains energy while oscillating. It's "perpetual motion" in the "orbits forever" sense, not the "free energy" sense. Also has nothing to do with quantum computers.

Time crystals have no direct relation to quantum computers.
Quantum computers currently are very limited, but may be able to eventually compute Fourier Transforms in an amount of time that's a polynomial function of the input size (aka polynomial time), even for large inputs. That would be really cool! There are a few other problems they can solve for which there's no known classical polynomial time algorithm, but the Quantum Fourier Transform (QFT) is the big one. AFAIK nobody has yet managed to even factor the number 21 with a quantum computer, so they're a tad impractical still. Also there's no proof that classical computers can't do everything quantum computers can do just as efficiently (i.e. that BQP ≠ P), but it is strongly suspected.
Quantum annealers like D-wave's do exist now, but solve a more limited set of problems, and can't compute the QFT. It's not certain whether they're even any faster than classical computers.
I've made several enormous simplifications above.

They’re trying to play Star Citizen.

Yeah, like I mentioned in my first comment I don't really know anything so you may be right too. 😉
But I don't know, there's a lot of cool discoveries being done right now anyway. I did read up on quantum entanglement too because of this years Nobel prize winner in physics who used it to prove that the universe is not "real". How crazy is that?

Yeah, but you are dealing with quantum funkiness. There's always a catch, like with quantum entanglement, and how despite one's state affecting the other regardless of distance, you can't use it for faster than light communication, since the act of observing the state changes the state.

Beacn has two different but very similar products. One is more for mixing and the other does what this Elgato does (to my understanding)

Unless I’m missing something here. Aren’t both of these products for two different uses? The Beacn seems to be for audio mixing only.

I called it out on Twitter, and I’ll do it here: Elgato must feel threatened by Beacn.

Yeah 30000kW is an insanely massive number. The amount of power required to run that for an hour, could power my stack for 7 years.

Steam Deck too. Switch is Nvidia though.

True, a perpetual motion machine is impossible according to the laws of physics. But time crystals are not a machine, it's an entirely new kind of exotic matter on par with supersolids, superfluids and Bose-Einstein condensates!

just until series 5 rtx released and then it’s going to be a lot more!

The patent for what exactly? There's any number of GPU manufacturers. I don't believe any of them all have a common patent.

94 cabinets, 9408 nodes, each node is a Trento Epyc processor and 4 AMD MI250X gpu. Source from hpcwire, but I'm also an ASIC engineer for one of the chips :D
