> Has never actually been implemented with success due to flaws in human nature
The flaw is in Communism, not human nature.
The very system you claim could theoretically work - given enough technological development - is fully incapable of ever producing that technology to begin with. That's just another excuse in over a century of endless excuses for why command economies fail and fail so dramatically. That specific excuse regarding technology has existed at least since the 1960s. Fortunately, human nature will always thwart command economies.
They have a point, if you can remove the humans from the decision making loop, communism would actually probably work. But I don't think its possible to actually remove the humans.

If you look at how new technology develops, you'll see a lot of what goes into it is fundamental research carried out without an immediate profit motive. Science progresses through the open sharing of knowledge, take that away and the technologies we'd be left with would be far less advanced.

It is a commonly held misconception that communist societies are dictatorships. A dictatorship is as far from a communist society as you can get. What about those countries under dictators that claim to be communist? I'll give you a hint, they're not.
If you want to know what a communist society looks like...
True communism has a lot more in common with anarchism than the societies that got given the communist label in the 20th century. There are different schools of anarchism, but if you'd like to read more about it, I'd recommend starting with Proudhon...
