You haven’t understood. OP is saying that something being ahead of its time isn’t a function of how much time has passed since. It will always remain ahead of its time. As stated, it is an intrinsic, rather than an extrinsic, property.

I agree, and especially in this case, but I can think of corner cases where “its time” gets fuzzier as time passes and expands to include more competition.
For example, the Compaq Presario 2100 seems to have been about the first PC with a price under USD$1000 - I remember that being a big deal at the time! … for a few months. Now it’s just a footnote that took me some Google-fu to find at all, but it was ahead of its time at the time and was a cover story on magazines.
