Which of your favorite sci-fi tech seems achievable in a reasonable timeframe, say 100 years?

That wasn't FTL
That's not the part you were trying to say couldn't be done.
You were trying to argue that quantum entanglement couldn't be used to communicate, clearly it can.The FTL bit is the science fiction premise of the thread.

That is indeed that bit I was saying couldn't be done. Entanglement alone can't be used to communicate; a signal has to be sent conventionally over the distance.
The FTL bit is physically impossible, so it's not really "achievable in a reasonable time-frame"

I don't think we'll be able to upload knowledge any time soon, as we're a long way from properly mapping how the brain handles this.
But visual inputs for VR/AR is much closer, as there is already some functional implants for something similar: having cameras produce neural stimuli has been a thing for a few decades now, and it's now at the stage where some blind people have been able to regain a limited form of vision despite not having functioning eyes. The tech is only going to get better, so at some point it can be used to augment normal vision.
they had an ai generate images based off thoughts or dreams or something, I imagine its further ahead now too lazy to look for more articles https://www.nbcnews.com/news/amp/rcna76096

I suspect we will see a human brain to digital interface. I don't think it will be "downloading minds" or anything, but I could see someone finding a way to plug a specialized camera or mic in to have a full functioning robotic replacement part.
I'm pretty sure they already have the beginning pieces to this, but its too specialized and expensive to do anything commercial with it yet.
bsg, sga all had the brain interface thing going on. especially the cylon part was all about that.

Ai and eeg can read brain waves generate images already kinda decent, maybe meet the robinsons memory viewer machine.

Read the link posted. They already did it. In 2007. At a distance of 144km.
wrote on last edited by [email protected]I read it. Doesn't mention FTL, because that's not a possibility for actually transmitting info.
Edit: I think the way these quantum encryption systems work is that basically the photons (and I assume it's polarization being measured) become the encryption key to a message that is sent conventionally.
Like the sender generates a bunch of entangled photons, sends the paired ones to the recipient, measures their photons and uses the results to encrypt the message, the receiver measures theirs and gets the same results, the sender sends the encrypted message over email or whatever, and the recipient has the same key because of entanglement.
Meanwhile an eavesdropper measuring the photons would mess them up for the recipient so the message wouldn't decrypt. -
(I know nothing about this)
Could you to the sub-C measurement test enough times to show that it just empirically works, and then use it on that basis? Or are you saying that the sub-C measurement would prove that it doesn't work (and it produces random noise)?
I'm not sure what you mean by 'use it on that basis'. Yes, entanglement has been proven to work, but it can't be used to communicate FTL.

Nuclear fusion seems increasingly achievable.

Nuclear fusion seems increasingly achievable.
They are down to 2 main problems now. The main one is (the cost of) scaling up. Fusion reactors will be more effective then bigger they are. The tiny test ones are already past break even.
The other is wall material. Apparently the radiation has an annoying ability to transmute the elements making up the wall of the reactor. They are working out a material that can maintain its bulk mechanical properties, even with random elements appearing in its internal structure.

wrote on last edited by [email protected]No they didn't, they sent a conventional signal that was encrypted with an entangled particle. Nothing was sent ftl, this is like if I had two boxes that I know have the same thing in them, an encryption key, and traveled across the world, and sent you a message, you have the other box, the information in that box didn't go ftl you just opened it later.
there is no path to ftl communication here.
have a basic video on the topic: https://www.youtube.com/watch?v=9oBiS_Yb9Ac

The FTL is the sci-fi component that is the subject of the thread, the quantum entanglement communication part is the real world piece they actually got working.

This you?
I'm familiar with quantum entanglement. It doesn't work because you have no way of affecting which state you'll measure, and thus what state the other particle will be in.
That's exactly the part they DID get working.

Check out the app Phyphox, it uses all your existing sensors and probably surpasses tricorders in several ways while, of course, lacking in a few others.

Portable communicators. It would be slick to have a USB c tricorder though.
Download the Phyphox app to access your phones raw sensor data. Very much like a tricorder.
