I can confirm. I went a mere 6 months stuck on my phone in 2020 and it nearly killed me.
It started at the fingertips, and crept up my arms: heavy bruising and what looked like spider bites. By the time I got out of Texas, people were complimenting me on my weird PCB trace tattoos, and by the time I got a laptop again the red marks had started to sprout little WiFi antennae.
Having no healthcare, I had to bribe a surgeon in Chicago into surgically excising the communications circuitry spontaneously growing in my limbs and replacing my now ruined muscles with vat-grown chimpanzee biceps.
The bruising has mostly gone away, but the surgeon said that if I’d gone another 2 months they’d have to behead me, hook me up to a massive machine with a bunch of Tesla coils on it and do the whole brain transfer thing like in bad 50s scifi movies. It’s real, by the way.
So I have to agree that EoC couldn’t have possibly been entirely without a computer for almost a full year. At least regular computer exposure would be required.
