Well I'm a loner, with or without tecnology; but I think that tecnology is progress, like many people said: Tecnology connects millions of people around the world. So you can find people with the same interest as you (e.g: Pokémon at this forum) and be able to talk to amazing people. In other side; I don't think it make us lazy, just makes our lives more practical and easier in some aspects.
When I was young I used to play with N64, Game Boy, DreamCast... So if I wanted to play with friends I had to get outside and I didn't felt alone with their company. Nowadays if you wanna play with friends you can do it at your home, that's... Yeah easier and practical but makes feel lonely to some people.
I think that we all gotta make a balance to ourselves, you can use tecnology, yes... But not focus all your lifetime on it cause you'll feel like a loner somehow, like myself.
