"There seems to be no such thing" as high speed digital electronics. There wasn’t then.
"...neither on the basis of experience..."
...but we don't experience frozen light for the simple reason that we are not moving at c through the ether. If we were moving that fast, we would experience frozen light.
I sent a narrow spike (and also a step) down a spiralling conductor (Figure 6) above ground plane in an epoxy glass board. I probed the spike (or step) 120 inches and 234 inches down the line. Here was the same spike (or step). See Figures 7 and 8 (spike) and Figures 16 and 17 (step).

This is the standard signal from one logic gate to the next in a digital computer, which computers comprise 95% of today's electronics.
Except that I was seeing a spike (or step) and not a sine wave, I was seeing exactly what Einstein said "There seems to be no such thing, however, .... ". I could equally well have sent a sine wave town the conductor, and inspected it at various points. Like the spike (or step) it would have been frozen.
" ...but we don't experience frozen light for the simple reason that we are not moving at c through the ether. If we were moving that fast, we would experience frozen light." - John D. Norton .
I had the signal spiralling round in front of me, and could inspect it along that distance. With two oscilloscope probes, I could have inspected the signal at two points at the same instant in time - frozen. - IC
Einstein wrote ""There seems to be no such thing" in 1949, and high speed logic came in 15 years later. This is just one aspect, or insight, gained from high speed digital electronics which is doggedly ignored in this sort of discussion and in Received Electromagnetic Theory in general.
