That's ridiculous. We have managed without electricity or antibiotics for 100,000 years too. Are you keen on reading by candlelight or dying of preventable infections?
Instant messaging and calling is extremely valuable. Algorithmic social media is extremely noxious. Unfortunately, they both live on the same device.
Comparing smartphones to antibiotics is somewhat ironic given that smartphone addiction is a disease, not a cure to one. There is no law of the universe that says that technology cannot create ills where previously there were none. I assure you that you are allowed to turn your phone off for hours, days, weeks, forever if you so choose, and your life may be better for it.
A more apt comparison is would you be OK reading by candle light sometimes for a few hours? I would be, it’s perfectly fine to read for a few hours by a bright candle.
