Hoost personally was an up and coming fighter and to some degree the Dutch kickboxing scene was just developing although fighters like Dekkers had significant success. The idea you were pushing that K-1 represented a totally new sport in 1993 just doesn't hold up, professional kickboxing had existed for decades prior to that and K-1 was an individual promotion with slightly different rules.
Now K-1 did certainly draw in talent rapidly and ironically this is actually an argument for how HW MMA evolved as well. When the money became serious and promoters were proactive in signing new talent in advanced very quickly, Hoost, Aerts, JLB, Bernardo, Crocop, Hunt, Hug, etc were all around less that a decade latter. Whats more we saw what happened when that proative investment stopped, HW kickboxing became significantly weaker very quickly just as HW MMA has with only really the UFC around who spend barely any money on new talent(why guys like Ngannou who will start for peanuts are there new hopes).
The reaity is beyond the justification your posting hereis just blindly supporting whatever hype the UFC throw your way, sometimes that hype is legit, if someone claimed Dillashaw represented a fighter on Fedors level I would not be critical of them for example. Your a "Ronda Rousey 1 in a million" kind of fan though who gets highly defencive when people point out that perhaps just maybe you've fallen for corporate spiel telling you that every single thing the UFC is selling you is the bestest best thing EVER!.
Sapp had a couple of years training but honestly watching Ngannou fight Stipe I think the question isn't "how did this guy get so technical so quickly?" and more "how is this guy so lacking in technique after 5+ years?" that to me was a daming criticism of supposedly "evolved" modern training. Physically as well Ngannou looked more than a little like Sapp(who lets remember was 350lbs+) or Lesnar to me, big and fast but clumsy, certainly not something new to MMA.
Your bias towards Pride is making you blind, i don't give a damn about the UFC, i only care about fights.
We aren't in 2007 anymore, all this UFC vs Pride is ridiculous.

Ngannou is getting more money than the whole Pride cards, tell me how the UFC stopped investing money or some fantasy stuff like that.
MMA is getting bigger and bigger, there are more gyms and practitioners all around the world, fighters are paid more money than ever, this idea that the sport peaked a decade ago when the sport itself was 10 years old is ridiculous and nostalgia driven.
Believe what you want to believe, i already know that your aren't going to change your idea.
