In the end though, IMO many perceive forums like Bitcointalk as a relic of a bygone age. And unless all major social media platforms suddenly imploded, I don't think the situation is gonna change any time soon. However, if Bitcointalk upgraded it's software, supercharged it's attention towards effectively managing the community and put in effort into marketing itself, it might be able to regain it's position as the premier platform for crypto-related discussion for everyone.
There is this thing about relicts, they tend to gain value with time. I think it will happen here also.
Even in today times we can see how people react to old satoshis posts. Ton's of merits, threads are still active and links to his words are still being interchanged, discussed. This won't stop, you are right, its like fuel in perpetual motion machine.
I think bitcoin needs this place to stay a little archaic, out of time, mostly because it needs backstory. Some sort of a background.
In modern era conservative nature seems old-fashioned, pase even but nevertheless rock solid. Most stable constructions are built on bedrock, not sand and that's why this place is still alive, thriving in fact.
There also this; don't fix, what is not broken; rule, so in my mind this place is bitcoin the other side of the same coin, in some sense.
People just don't seem to realise this.
