Bill,
I do get the point.... But I would buy into a multi-paradigm shift. Sometimes popularity is based on capability, driving the social norm.
Commercializations of specific products drive sales and popularity. 75-100 lbs bows are not mass produced so they are not going to be promoted or popular, because the mainstream cannot achieve accuracy with them(nor does the mainstream want to put in the efforts to do so). The 40,45,55 lbs bows will seek, are available, and get the socialization and support from advertisement/commentary. It's the cookie cutter idea... And everyone loves cookies!
I am absolutely respectful of those that are conforming to what your body is allowing you to do, I have done some pretty serious damage to mine over the years and have enough bionic parts to give very accurate weather forecasts from spine to tibia.
I do say, judging by the work my elders are able to still do, swinging a 12lb sledge for hours, to what I am capable of and almost 40, to what my 20yr olds are capable of (in general) there is a drastic decline. At 35 I was working pretty hard to keep up with a gentleman twice my age swinging an axe splitting wood, and I'm pretty familiar with doing that. At 37 two 20yr old privates were struggling to keep pace with me swinging pick axes to dig a parallel whole to mine.
Really the requirement for work no longer exists, so the drive and capability to do so will fade. We have come to know that lower poundage, sharper broad heads and heavier FOC will kill effectively, so there is no longer a need to work to achieve what we once did. Thankfully so at times.... But with that we drift into the same root of hunting discussions, that all the sent locks, attractants, feeds a ad dance do-dads have made us less capable "hunter" while maintaining the same Kill ratios or better than previously achieved by those with more woodsman ship than we may ever see again in our lifetimes. Bringing most of us full circle back to why we chose to hunt with stick and string, that primal urge to truly feel the hunt again. 40 lbs or 100lbs, most are here out of true respect for what God has given us, feeling that deeper connection in the woods with stick and string, than cruising the back road in a pickup with a smoke pole.
God bless everyone of you, every story, every newbie question, everyone who spreads that true love of woodsmanship. I'm far from where I want to be, but you all help me stay focused on getting there. That desire to be back emir see in nature carried me through a lot.
