No telephone to telephone is a HUGE change. Telephone call to digital PBX over fibre to packet switched VoIP to WhatsApp feels like no change at all.
I don’t really have hard data that proves the impact of the internet at a macro level, just anecdotal stuff. I think it’s easy to overplay the impact of past innovations bc we see the late waves - eg the telephone wasn’t really a thing that impacted most of the world for decades, and there’s entirely countries that went from no telephone at all to whatsapp directly (brazil for instance)
When it comes to jobs, I think I know maybe a dozen people whose jobs/industries only exist because of the Internet - and that’s counting outside the tech bubble, mind you. I’m sure this is verifiable with labor data somehow. Not to mention the entire middle class slipping into gigs in a model that only exists because of the internet (maybe a bit too recent for most to grasp the consequences).
On a personal level - quite literally everything in my life would’ve been completely different. I can’t even imagine the kind of local job I’d have at a small town, watching about stuff on the TV and hearing about tech only from a friend over radio
