I think the hint is in the examples you're giving : the 1970s were the heyday of progressive and what is now called "classic" rock, and that particular genre seems to be your frame of reference.
Whereas for us Euro synth folks, the 70s was the age of early pioneers like Kraftwerk, Vangelis, Jean-Michel Jarre (I suppose that's where rock music was in the 50s)
And the 80s are THE golden age of synthpop explosion that put us on the map, with legends like : New Order, Yazoo, Depeche Mode, Soft Cell, Bronski Beats, Eurythmics, Jean-Michel Jarre, a-ha, Tears for Fears. Our 80s are rock music's 60s (think Beatles & Rolling Stones).
The 80s are so revered that for the past 5-10 years there's been a whole music genre ("Synthwave") dedicated to reproducing its aesthetics with a contemporary twist. It's even been preempted by mainstream pop recently with The Weeknd's "Blinding Lights" single.
Our own Led Zeppelins are 90s kids Daft Punk, Chemical Brothers, the Prodigy, Fatboy Slim.
In the 2000s, we took over for good and mostly killed any remnants of rock music's mindshare in Europe, and the US followed in the 2010s with the "EDM" mainstream pop flavor of our stuff.
In other words, it's all a matter of which bubble you're living in !
