Very deep question. I've thought about this on all fronts. The truth is that man is wired to never stay in isolation and that no matter how independent we say we are, we would always need someone.
No wonder we were not made one person per planet.
So back to the question, we keep doing what we need to do, someone out there is dying to meet you even if people around don't seem to need your services.
Now but, at what point are my skills no longer able to compete with or improve those of machines?
The moment we stop improving, the moment we stop developing and creating alternative solutions to ever dynamic challenges of life..
