I've been thinking about how fantastically more difficult this whole "work at home" and "remote collaboration" would be with the "internet" of only a few decades ago.
Think back to when "getting on the net" meant firing up your desktop computer (with CRT display), dialing in to your service provider with a modem, and then waiting for things to load. Even at the then-blistering speed of 57.6Kbits/sec, some stuff took minutes before you saw it. Prodigy, AOL, Apple Eworld, MCI Mail, etc. were some of the big names.
The hot new connection with maybe a megabit or so per second was a cable modem, but cable companies insisted on renting them to you. You might be able to buy a modem yourself, but the cable company might not allow you to connect it.
Companies with significant out-of-office work forces would often maintain racks of dial-in modems to answer lines. Each one took a dedicated box, telephone wiring, computer port, etc. along with the staff to manage and maintain it all. And if a whole lot of co-workers dialed in at the same time, too bad for all the latecomers, even if you had a work deadline to meet.
In theory, a cell phone might support a data channel, but it was mostly like a dial-up wired land-line, with the bonus feature of frequent dropouts and radio interference to trigger random hang-ups.
Oh, and let's not forget fax. Fax was where the future of business automation had people writing out orders on pieces of paper, then carefully feeding them into a slot on a little box, and praying that the paper wouldn't jam. When you think about it, a fax is basically a machine for sending telegrams, complete with the requirement for using paper as both input and output, as if CRTs had never been invented.
