Don't worry about it if it won't matter in 100 years
I always kinda brushed it off, and found it was useful to tell to others who were upset but not for yourself.
I was thinking about it just now and realized what if we started looking at things with 100 year glasses.
What would change, what things would matter?
I agree with Elon Musk (and I'm sure plenty of others) that becoming a multiplanetary race is a good thing.
I agree reducing our reliance on oil is a good thing (however I feel that reducing our need on energy in general is a good idea).
I agree finding a way to diagnose and resolve health issues without the need of doctors from your own home is necessary.
If resolving transportation issues is a need we as a people can and should solve it.
We should focus on furthering the human race more than helping a company making 100 billion dollars.
How can we still maintain a level of our fellow man while automating the unnecessary things? (some kind of robot to cook healthy meals for us in our own home)
If we can imagine it, and focus on it. We can build it.
Not everything should come at a cost.
What can you imagine we need built 100 years in the future with the will of our people?
