Seems to be going the opposite direction, if you ask me.
There was much more demand for master seducer instruction during the 2000s and early 2010s when guys were excited about pickup and out practicing.
As skills decline, fewer and fewer people want training in a skill in general, and the skills of a master practitioner become valued less.
Most of the master practitioners of game I have known over the years dropped out of the field because it's just gotten harder to earn a living doing it and they're better off starting companies focused on XYZ other thing unrelated to anything have to do with seducing women.
If you ask me, the level of dialogue on the Internet was much more advanced in the past. You had detailed, lengthy forums on everything, experts all over the place, it was this web of people sharing deep knowledge.
Now most of the forums (not just in seduction, but most places) are dead. People are on Reddit, where the level of discussion is low; Facebook, where the level of discussion is low; Discord, where it's somewhat higher but knowledge is far less accessible.
Blogging has died down quite a bit. People live on social media sites and get their attention highjacked by sensationalist stuff (fear-mongering news, attention grabbing social media posturing, etc.) and don't have the energy for the more thoughtful stuff that used to dominate the web that's not simplistic + sensational.
There'll always be some corner of the web with advanced folks having advanced discussions for most things, I'm sure.
But the web has been following the "Master Switch" trajectory for some time now:

Personally I have a harder and harder time finding expertise in anything I search for online. Web search is dominated by simplified beginner results, because that is what performs best on Google / gets the most clicks / has the most satisfied searchers, and all the niche stuff gets pushed to the bottom.
I don't think most people are frustrated at the lack of advanced methods.
I think most people are frustrated that the beginner methods aren't even
simpler.
There is this big push to make things as simplified and bite-sized as possible.
That is the opposite direction from trending toward cultivation of advanced stuff.
The collective ethos of the 2020s Internet so far as I can tell is, "It's too hard! Make it easier!"
