You are not talking about technology,you are talking about philosophy.
On one hand,advanced technology is bringing us convenience,leading us to explore new worlds,teaching us new knowledge; On the other hand,human-being is losing the rights of self-evolution,and he chose evolution of machines instead.
It is definitely not about wars,environmental problems,climate changes or even human extinctions.Without technology,human would also make and solve problems above,but much more slowly.
The limit of technological advancement,I think,will lead human to his mental & psychic evolution,and finally give human a full-new ability:psychic and telepathic power.
This topic has been discussed for years.You can read the friction named " Der Physiker".I believe you will think more and deeper.
