I for SOME FUCKING REASON cannot open the reblogs on this to find the original chain I'd responded to. #FunctionalWebsite.
I think the trick here is simple.
Cuz some people have pointed out that there's an *easy* logical flow here, but like. There's a step that's crucial.
People didn't have access to mobile phones in the 70s. Or, well, that's not quite true... Wikipedia diving for me.
The first handheld cellular phone was demonstrated in 1973. And weighed 2 kilos. The first commercial cellular network analog was in japan in '78, followed by launches in '81 in Denmark, Sweden, Finland, and Norway. Prior to this, there was Radio Telephones, but these were primarily mounted in cars and trucks, and briefcase portable models were... Well they were *briefcases*.
The cultural phenomenon is that nowadays not only does literally everyone have their own personal phone, but that it also connects to... Well.
Remember that ARPANET was '69. The 70s was also the decade where the internet was first being *born*. The Internet Protocol Suite wasn't standardized until 82.
So we have these devices that connect to a global network of information, shopping, socialization, movies, games, music... All of us, now, individually. Which is a combination of the idea of the telephone and... Ah,
"Home Computer" was the way people called them in the late 70s, early 80s. And the way *we* think of them in the modern day is also deeply influenced by the idea of the graphical user interface, something that makes computers more visually designed rather than purely text-based as an operating system. And the first commercially-available computer with a GUI was... '79.
And of course, they still use electricity. We've moved past... Well, hold on. Were they still using batteries in the 70s? Hell, even if the technology for Rechargeable, Built-In Batteries was a thing that far back, USB cords weren't designed until '96, which is how nearly anything is recharged these days.
So for the convenience of people who have palm-sized computers in their pockets, so they can readily connect to a global network of information that's like radio but even fancier, we've designed some expensive couches to have built-in ports for the relatively standardized cables we use to charge them.
then we can land on "and also the doorbell is equally portable and uses the same rechargeable technology (and possibly the same connection to global networking), so it's easier to manage if e.g. your original doorbell breaks down." Which is the part that I think people have kinda glibly said is the easy part to explain. And even oversimplify.
The choice of the 70s feels really potent here, because someone in the 70s could have exactly enough context to be completely boggled with not only How, but Why we ended up here. Like. The further you jump back the easier it is to sort of... I'm gonna say "magicalize" a lot of modern tech. Which, to be fair, a lot of modern tech feels like fuckin' magic. We connect to a network that we've formed in the very air around us, powered through harnessing of the energy found in lightning, and it lets us communicate all sorts of things to each other from anywhere in the world at speeds only tales of magicians being able to teleport could hope to achieve. Not even your fastest athletic heroes could outrun it.
But the 70s lands right when a lot of foundations on this tech were just being born. ARPANET was only a few years old, "WiFi" isn't until '97. Microprocessors were just being born and now they're so ubiquitous they're in fuckin' *doorbells*. That thanks to that ubiquity, the need to recharge it is also so supplied for you might have a couch with a convenient port for it!
