Realism is not even remotely the point of high level story telling. All fiction is non-realistic to a very high degree because unfiltered reality doesn't make for good stories.
Also, judging a story based on how realistic it is and nothing more is the definition of putting Form over Substance.
Wrong.
I have been posting about quality of writing and entertainment.
Star Trek, purports to be a "realistic " depiction of the future. One that is a logical extrapolation from the mid 1960s and beyond.
Problem: since the 1960s, in terms of some things we are far more technologically advanced than Star Trek ever thought of being. But NOT in terms of Artificial Intelligence. Star Trek had Artificial Intelligence before 2002. Please note that this doesn't mean that electronic computing technology is more advanced, because it turns out that Gordon Moore's law, was expected to be good only for ten years after he formulated his law...
Then there is the problem of the DY-100 interplanetary ship...while it was quite likely that a plasma driven ship could have the necessary performance level, it was never done. Manned Spaceflight at this time, is basically a joke.
Why?
Because Nixon chose the Spaceshuttle over the nuclear rocket.
He brought advanced space travel to an end.
Right now all we hear are excuses for 'why not '.
The United States had the technologically capability to send people to Mars, as as 1978.
Which brings us to the real problem.
We don't know enough about Manned interplanetary flight, and the actual problems that will occur. What we have is guesses, not hard core empirical data.
To get hard core empirical data requires actual informed sacrifice. Meaning actually sending people out on a full up Manned mission to Mars. No guessing permitted.
This is the difference between fiction and reality.
The 'will' doesn't exist. It has been shot down by fear and trolls...
Hard lessons half to be experienced and understood.
Now in terms of the projected future in Star Trek, Eugenics wars of the early 1990s, far more than problematic.
'The Expanse' has a far more realistic depiction of Interplanetary travel than Star Trek...
This brings up another point. We now know far more about the Solar System, then they did in the 1960s.
So, this is why I prefer quality to quantity.
Star Trek, was limited due to lack of data. This is our major problem. Our ignorance.
