That's like saying the technology is there for fusion. If right now I pull outta my pocket the money to put a fat Bigelow complex on the Moon, lots of tech would be missing. It has nothing to do with my personal expectations. Don't be childish.the technology is there ....no matter how basic, it is still there.
Apples and oranges. You don't specify what the 1971 cpu is tasked to do. Could 1971 have used its CPU know-how and concrete means to do something otherworldly for 1971? Sure. But that's a vague statement.In 1971 we could have had this same exact argument about the first microprocessor. The technology existed and was in use, but it was nowhere close to being ubiquitous like it is today and we could have aruged about its viability as is.
In so many words you waffle between refusing to admit that the technology is not ready, and downplaying its tardiness. What's the 3 large rooms analogy supposed to do for this specific argument of whether closed life support tech exists? Is that kinda tech supposed to be about to mature to in the next 5-10 years? Show me this TRL 3-4 tech already. It's not a complicated request, just point me to it.Regardless of those arguement, the technology existed ...despite being an infant. Look at where it is today in comparison. If you would have told someone in the 70's that they would have the computing power of 3 large rooms worth of computing power on a device with no wires that would fit in their pocket ...you would have been laughed at.
