A few decades ago if you saw people walking alone down a street talking out loud you’d have assumed they were insane.
Today you just assume they’re using a cellphone.
Back in the 1930s when George Orwell wrote 1984 it was science fiction that someone could watch you in your home from far away, or that you could cook a meal in a few minutes.
Today those things are the norm.
In the days of my youth if I sent a letter to someone who lived on the other side of the continent it took at least a week for them to get it and another week or so for me to get a reply.
Even expensive long distance phone calls took a while talking with the operator and waiting for a connection. If the other person wasn’t home there was no way to leave a message.
Today we can send messages to each other in a matter of seconds and people can receive them at their convenience.
And I remember when fabric that didn’t need to be ironed first became available. Today most of our clothes are made of synthetics.
Maybe eventually instead of cellphones we’ll have brain implants. Then some evil world government will use those to control us all.
