Could one really really smart person eventually recreate all technological advancements granted immortality?
Let's say we left one single very smart guy (not necessarily with the knowledge: they may be able to understand hard stuff when taught it, but not know it already) alone on a copy of the earth. That person is also immortal. Could that person, by themselves, gain back all knowledge, maybe also experimental, or even surpass that is already available to us right now, before the planet gets inevitably engulfed by a sun turning red giant?

What transmits the information, I don't understand. The rocks just sit there. Don't get it. The guy maybe?

It can be hard to explain, but basically each row of rocks is a line of input/computation/output not unlike the binary code that flows through the circuits of a processor. It's a different representation of the same kind of work your device is doing right now. And, as you might think, waaaaaay slower.
Yeah, what is slower though. Presumably they mean the rate at which the guy lays the stones, otherwise there's nothing changing over time. It would just be a record.
Right. Think of Cueball laying stones as a CPU, and the rate at which he can finish laying a row and return to the beginning as his clock speed.
Very long lines, then.
Mind-bogglingly long!
ah, so I see the guy has started resorting to the pens that fall
