can/must

Just because we can do something doesn't mean we have to do it, and just because we posses something doesn't mean we deserve to possess it.

I read an article that said the coming revolution in artificial intelligence and automation is going to cause social upheaval as millions of people are thrown out of work. Self-driving cars and trucks eliminate the need for taxi drivers and truckers, self-checkouts eliminate the need for cashiers, robots will cook the meals in restaurants and assemble consumer goods.

But we don't have to build those things. We can leave things the way they are, or even go back to a simpler time if we want to. If a robot is going to ruin our lives, then lets not build it.  It's not "progress" if it's making everyone unhappy.

And on a different topic, Republicans believe that because they have accumulated a pile of money it logically follows that they deserve to have accumulated a pile of money; and furthermore, it would be a sin and a disgrace to tax that pile of money to take care of the people they took it from.

I don't think it's wrong to expect a little better than that from people.
