How will the world end?

I think everyone will turn into recluse's and not leave the house... this meaning they can not make babies and humans will just get old and die off.

These days everything can be done online, shopping, chatting, ordering food, running a business, for some people there is actually no need for them to leave their house... a perfect example of how the internet for many things is amazing - but also has the ability to ruin lives.
