When Yosemite Mountaineering School classes went out to the rock they used nylon ropes, in 1975. I was never more than a student of climbing but everything that has been mentioned in this thread was being done, and written up in books you could buy at Kelty, in the mid 70's. Dawn Wall was climbed with 300 bolts on its first ascent (but bolt usage was ahead of its time). The 'harness' is the main refinement I would say was lacking. YMS classes were taught to put on, and the books described, the swami belt (not unknown today, but not preferred?) made on demand from webbing. Cams were advertised but chocks/nuts were the standard.
I doubt cams were advertised in '75. Friends were created in '78.
Greg Lowe’s cams predated friends by about 3-4 years
Not just nylon ropes, but multi-fall ropes: in the early 70's, we didn't trust a rope after it had taken a hard fall. You can't learn a big-wall route if you have to retire your rope after every long fall.
Yes, but isn't that also roughly when modern sport climbing started?
Nylon ropes for climbing were introduced about 55y ago, though, I don't know when they became wide spread. Same for modern harness, modern bolts and quick draws. So your ~40y ago might be roughly correct.
Modern sport climbing started, I would argue, around that time. For instance, Red Pointing was popularized in the 70ties [2].
Also interesting is, that Phoenix, the first 7c+, the grade of the route in the Free Solo movie, was climbed in 1977 [3,4] and first free soloed in 2011 (also by Honold).
