Anyone remember Java 3D? 'cause I'm imagining Java 3D!

I don't understand your reference. It seems negative, but it's hard imho to go down on the success of Minecraft. Or am I misunderstanding you?

Does superconductivity remove or reduce the limit on die size?

I'm making a naive guess here. No, superconducting transistors are probably harder to create than non super conducting transistors so the limits on die size from defects are even more pronounced and superconducting doesn't change the speed of light for electrons on the chip so it doesn't change the timing issues arising from large dies.

Given the cooling requirements, I suppose it would create completely impassable rift between datacenter computing and other kinds. Imagine how programming and operating systems might look in a world where processing power is 80x cheaper. Considering that "data centers alone consume 2% of world's enegy", I think it's worth it.

I don't see an impassible rift. Probably at first, but supercooling something very small is something that could certainly be productized if there is demand for it.

I can see demand in areas like graphics. Imagine real-time raytracing at 8K at 100+ FPS with <10ms latency.

If implemented using switches based on the Josephson effect like here, then no.

The thickness of the required insulating barrier presents a hard lower limit to the structure size.

The actual value of that limit depends on the material used and the particular implementation of the Josephson junction, of which there seems to be quite a few.

So the limit depends on how thin the barrier can be made.

Minecraft (obviously the Java edition) actually uses some native libraries (LWJGL) so I don't know if Minecraft is a good comparison.

Solid state physics begets both cryogenic technology and cryocooling technology. I wouldn't write off the possibility of making an extremely small cryocooler quite yet. Maybe a pile of solid state heat pumps could do it.

Can't imagine why it would, but the lack of heat makes a 3D cpu much more feasible. So you could take 20 die, make 20 layers, and get radically more transistors per volume.

Javascript emulator in Javascript!

Do you mean the "eval()" function?

Subtitle from the link: > The 2.5 GHz prototype uses 80 times less energy than its semiconductor counterpart, even accounting for cooling (emphasis mine)

Yeah, but only at datacenter scales. > Since the MANA microprocessor requires liquid helium-level temperatures, it’s better suited for large-scale computing infrastructures like data centers and supercomputers, where cryogenic cooling systems could be used.

DC scale is great. Most stuff runs in a DC. What's wrong about requiring DC scale?
