If you want to seriously maintain this claim, then you are basically arguing that the subforum is unjustified.
What claim do you think I'm making?
So, why doesn't Bones recommend lasik surgery instead of Retinax V? Under the reality criterion (if we allow for extrapolation), it seems highly unlikely that Kirk would be limited to glasses. Why wouldn't Bones recommend something more convenient that glasses? If, however, the future is sacrosanct and unknowable, all we can do is shrug and suppose there must have been some good reason -- the game is over and we are reduced to being passive observers.
We don't know what Retinax V does. We know it's the standard therapy for myopia and/or presbyopia, and that some people are allergic to it. McCoy's recommended alternative to Retinax V for Kirk was a pair of reading glasses, antique ones at that, as Kirk has a fondness for antiques. Would every other physician recommend glasses instead of Retinax V? Are there any other alternatives - Retinax VI perhaps? Can't say.
Rather the Treknology game is one of comparing one guess about the future against our own best guess about the future.
Is that what it is? Are you sure?
...You, however, would obliterate this criterion, bringing all of our discussions to a standstill.
Me? What??

My argument is that you reach a point where the fiction lies so far in our past that it is no longer profitable to play the game this way.
And I think the rest of us would say that Trek is not that far in our past yet.
EDIT: A Note About the Coming Singularity for All You Biomeat Puppets
Your objection was to linear extrapolation. The curve of modern technology, however, is often curve-linear (e.g., Moore's Law). If Ray Kurzweil is correct, then you are more right than you know about our inability to extrapolate future technologies! Star Trek is in many respects a linear extrapolation to future technologies. Since no one can say what exactly is on the other side of the singularity, we can have no reasonable discussion about Treknology.
I don't think Kurzweil is correct, and I don't think you can predict or foresee a singularity. I don't think a singularity is at all inevitable, as you seem to think.
In actuality, the singularity hypothesis is not that stark. It proposes a fusion of man and machine and the arrival of machine consciousness, so it does make some positive claims.

Either way of reading the singularity (either as a true unknown, or as a mostly unknown that follow human-machine fusion and machine life), however, basically makes Star Trek steampunk(ish). Whatever the future is, it ain't likely to be analogue gauges and portable memory cards the size of a ham sandwich.
We already had a discussion about what steampunk is and what it is not. The definition is clear, albeit recently formalized, and it's not helpful in discussions for you to twist the term to your liking.
What I am saying is, if you want to make the nuclear move, I can adapt to it. I might (then again I might not) have to give up my particular critique, say that analogue gauges have no place on a starship, but consider the outcome! We would not be able to say anything reasonable about the future Trek might inhabit or reflect. ----Game Over---- I, however, could still argue for an alternative criterion that has no pretensions to knowing the actual future. I would, in effect, be the only game in town.
What's the "nuclear move"? I have no idea what that means to you.
I'm interested enough in your proposition to continue a dialogue with you, but I really have difficulty understanding your position and your proposal. I think it would help if you would give examples in other threads here, instead of detailing and pushing your idea in just one thread.
