>I find it interesting that when watching old movies, few got the communications networks of the future right

There's some old video made in the mid-1960s showing "a view of the future", which basically depicts every home as having a home computer connected to some kind of communications network, where people would be able to read news, send messages, and even do shopping.

While a lot of sci-fi really seemed to miss the bus as far as communications go, there were some people who really did see what was coming. For some odd reason, they never got involved with anyone who made movies. But the internet really is pretty simple and easy to understand to an intelligent person from before the internet: they had news programs and TV, they had newspapers, they had magazines, the had snail-mail, they had telephones, and they had mail-order (and telephone-order) shopping. All the internet did was tie it all together and make it easily accessible to everyone, which had gigantic network effects that were unexpected.

>But on the other end, we have lots of movies expecting much more from us on the 'space' end of things. Many movies that occur in space have us already having permanent moon bases in the timeline.

That's because those movies were all extrapolating, accurately many times (like with 2001: A Space Odyssey), based on then-current trends in aerospace technology. Just look at the progress of aerospace between ~1900 and 1970: we went from just figuring out the airfoil wing to making airplanes that decided a world war (II, they had a good part in I too), to making supersonic planes, to making rockets and then landing men on the Moon. That's pretty remarkable progress for 70 years. After that, what have we done for the last 45 years? We've sent out some neat deep-space probes and rovers, we've had a few rickety space stations in LEO, and we've made passenger aviation much more ubiquitous and inexpensive, and (related) improved fuel economy. We haven't progressed remotely as much. We've made huge strides in computers and electronic networking though... We've also made some big strides in medicine. If we had kept up our attention and funding in the space program like we had in the 1960s, we would have a rotating space station and a Moon base by now.

>"Seveneves" by Neil Stephenson mentions our modern communications software at one point in the book, how it alters our brains, and how future civilizations avoided the same fate intentionally. However, I'm not about to make a causality assessment between our communications software and our lack of advancement in space

I will.

We cut back our funding for space exploration long before the Internet became publicly known. The Internet was conceived in the early /mid1970s IIRC, and only become commonly-used in the 1980s in academia. It only became known to the general public in 1989 thanks to Robert Tappan Morris and his worm, and only become generally used by regular people in the mid/late 1990s after the invention of the WWW and the HTML browser. By contrast, the funding for space exploration was cut in the early 1970s, before the Apollo missions were even done. There were a bunch more Moon missions planned; they never happened because Congress cut their funding and redirected what was left to the bloated and ill-conceived STS (Space Shuttle). Things went downhill from there. In a nutshell, once the US landed men on the Moon, the "space race" was considered done and won by the Americans, so the Soviets mostly gave up on such highly-ambitious goals, and both space programs instead turned to much more practical matters, namely coming up with ways of more cheaply launching spy satellites, navigation systems (GPS, Glonass), etc., instead of giant national-prestige projects that served no military use whatsoever (but instead advanced science and civilian technology tremendously). The US had given up on things like a real space station or a Moon base long before the Internet was something people had any serious interest in using.
