Already posted! Go back half a dozen posts to see it. But I appreciate article suggestions.

hot damn- Quantum Computing is advancing so fast . . . two different methods towards Quantum Computing, both make pretty similar advances.

I mean there's like many different ways of doing Quantum Computation - ion traps, superconducting, spin, photons, topological insulators/or a kind of quasi particles. The ion trap guys were saying they were the only method towards reliable qubits.

Everyone's ideas of when, lets say, the Star Trek future is coming is probably not very accurate.

Exciting times. But I don’t think we will ever see a world very much like Star Trek, except virtually—mainly because they have too much technology unsupported by even theoretical possibility, and because people in Star Trek largely remain regular biological people. I strongly suspect that when people can enhance themselves technologically rather easily and without negative consequences, they will.

Well, I can't imagine "beam me up Scotty" even though they've done everything from quantum entangle lasers to holograms(close relative to lasers), to LIGO getting their mirrors to the quantum limit of thermodynamics.

I remember an article over a decade ago that showed how much quantum entanglement you'd need to beam people up Star Trek style. It would take a very mature nanotech and quantum computing era to do that.

There's also lots of warp drive theory going on, suggesting that may be possible. I'm not sure that means twenty five times the speed of light or something like that. It's more like being able to get to light speed in pretty short order.

They've got all kinds of Star Trekish medical devices that can tell cancer by your breath and such stuff.

I came up with my own technique for teleportation years ago. Basically, you use disassemblers to take a person completely apart and store all the information on a computer, then use a laser to beam the information to a receiving station, which then reassembles the person using matter at that location. That should be possible with mature nanotechnology if a person can be successfully disassembled without losing any information at all. Such disassembly would probably take time, as would reassembly, so I don’t think it would be practical for relatively short trips, but it could theoretically work as a way to travel at the speed of light for distances as close as the moon and as far as the outer planets. Perhaps even interstellar trips. A robot would have to be sent first to set up the receiving station and assembly factory.

Ha ha - that's a good one. In a similar way that you say you have to go and set up a portal already, I had thought that before you can take your wormhole to some place light speed can't get to anytime soon . . . someone had to of already gone these great distances and already set up a wormhole. And, I've thought, maybe that's why you're not seeing E.T. They haven't set up a wormhole here first.

I've also thought that to use a warp-drive that we're discovering is to make a very energetic front. If you were to go light speed or faster to a distant star system, you'd probably wipe out whatever planets and/or life was in those star systems. E.T.'s might be "being nice" by not warp driving into our solar system . . .

Very cool…but it’s Chinese. Grr. https://youtu.be/h74Xj-WWwBc?si=mgYbSTTLUxVixZQV
