Trevor, I know the whole point of GVR is looking back but I'm not convinced things went downhill from the 60s and 70s. There's always a temptation to look back to a so-called golden age but it was rarely as golden as all that.
In my own professional field of broadcast video I look back to image orthicon and plubicon cameras, 2" and the start of 1" videotape, all analogue video paths etc. By the 1990s we had CCD cameras which could outperform anything that went before at lower cost and weight. Digital videotape that could go to any number of generations without loss and all sorts of digital systems. Even in analogue we had good video rated opamps starting with the EL2020 that made life a lot easier for the designer. And this is just in one small niche.
