The RDA can't do physics

Oh, yes. Sorry. Derp.

Yes, in parallel - requiring a different multi-billion dollar system for each one. I thought you were the one complaining about cost, now you've switched track to fantasising about the film you wanted to see?

You need a few micrometers of electronics for each particle. That's going to cost, what, a fraction of a penny each? I'm talking about building more cells of a SSD, not building multiple disks. You don't need most of the actual device to add more particles to it, you just need to duplicate a very small chunk.

Without distances on an astronomical scale, the time change is less than a single clock cycle. You can not do anything on a single clock cycle other than the very basic instructions. If they do attempt to use it as such, then the data needs to return, with a 4.4 year light speed lag.

Gravitational time dilation. The time dilation factor between here and geosynchronous orbit is +664ps... per second. Put one end of your FTL communicator on a satellite for a year, and then take it back down to Earth, and the accumulated time difference will be as long as 20ms. In the context of high-frequency trading, that's a very long time indeed.

I said potentially. If it isn't, that just digs your hole even deeper.

In the 1950s, CPUs cost millions of dollars each. Look what happened.

Only if each bit had a defined exact time to transmit or each transmitter was only used for a single bit per packet.

Isn't that the default? That there is a window of a few fractions of a second where you transmit?

I know. Don't profess to greater knowledge here than me - each error bit reduces the chance of detection of others, and increases overhead - in usual applications, bandwidth is far less of a concern than noise itself, as the more complicated an ECC implementation, the more data overhead it creates.

Yet you said earlier that you would run into problems because you need to receive all the bits

That seems marginally more realistic an assumption, but it still doesn't show that other humans should not be there.

Each human costs you literally astronomical amounts of energy. That's why they shouldn't be there.

Depends on what's at stake. Determining the difference between lifeforms and making a judgement that could have such huge repercussions is very different from following defined traffic laws (and assuming that others will as well).

What do you mean, "assuming others will?" Nobody will, because they're human. A huge amount of the difficulty of this sort of thing is predicting how the world behaves and reacting to that before it's happened. That's the exact same "skills" that would be underpinning a military defense computer as well. And what do you mean, "huge repurcussions?" People die if your auto-car does something wrong, just as much as they die if your military computer does something wrong.

...Except the circumstances where a human will be in its range will be exceedingly rare indeed, because normal operation will have all the humans cosy inside Hell's Gate.

That may potentially work, but there has to be some reason it wasn't used - there could still be a reason it doesn't work - even if it's signal strength or light speed lag.

It worked fine for the avatars. Then again, radio is easier to get working.

Hang on, I thought we were talking about communication within the magnetic field here. Stop jumping form one topic to another for the same argument.

I am. IMO, the most practical way for the robots to communicate is with radio transmitters connected to them via optic fiber. That cancels out almost all your EM interference. The R&D comment was about what you do if you don't have these technologies completely lined up; you develop them, because they will save you tons of energy.

I'd contest the second, certainly, but that's beside the point. A rate at which things are developed does not mean any research will instantly complete, ever.

It means that gambling that the technology does not advance gets riskier and riskier as time goes on.

...unless they were looking for minerals available outside Earth's solar system, exactly as they were. They most likely already are utilising resources found elsewhere in Earth's system including asteroids and potentially comets, the next logical step is further. No resource in the solar system lasts forever even if humanity WAS planning to only ever live there.

The location is irrelevant to the odds of whether the gamble will pay off. You're gambling astronomical amounts of energy on the assumption that technology will not advance in the wrong way. If it does, the price of unobtanium plummets and you've lost everything. Accepting that gamble is not good business sense.

And you'll find that the resources in the solar system will quite easily last long enough for the Sun to expand and destroy the inner planets. They just need to be exploited properly, which the RDA don't have the technology to do circa 2154.

Useful? Possibly (yet you fail to give any examples) - but profitable?
Surprisingly, there isn't unlimited use for energy anyway.

Rent out O'Neil cylinders.

...and when it is reachable?

...It'll be reachable if and only if it's cheaper.

Yet it doesn't instantly make it possible. As far as we can see, the former has not happened yet, and while the latter MAY be possible, it's still a long way off if so.

If it's conceivable that ti could happen, it's not good business to send an ISV.

That level also varies by superconductor, with some available today requiring >100T to do so.

There's still an upper limit somewhere, probably limited by current more than B-field.

No, but if the amount of said infrastructure is growing, the savings are too.

If the amount of infrastructure is growing, then you're pumping money into it. Obviously you're savings increase if your investment increases.

For about the fifth time, option 2 is not an option at this point in time.

Then wait for it to be an option. You might have to invest trillions of dollars in research, but you will save 6 orders of magnitude for every penny you spend thereafter.
