People CANT survive without internet.
I'm wondering how did my ancestors survived in the past without internet?

The economy was much less efficient and people had a much lower standard of living.
Bullshit.
For a lot of essential functions the internet only saves a meager amount.
I have already dealt with institutions that that calculate with "ok, and what happens when a tank blows up an office?" type of events. Internet is a "nice to have" to save a couple of expenses, but its very far from being essential.
