Really appreciate for all your valuable input!
I will leave them alone in stone age. I do not want to force or convince them, it is really hard to change one's mind, just want to let them know the good side of technology, freedom and eventually release from being a financial slave, do what them want, help people in need. At the end, the choice are theirs.

I am heading to this goal and hope all of you can help each other who willing to change to achieve too!
