Either you make them at work or in clubs or somewhere else you do organized stuff.
Or you just make them in public by doing random stuff.
Yea, regardless if you travel abroads, fly quadcopters in various places, climb mountains or base jump or fly planes or surf waves or something, people with related interests (or even unrelated people - like some base jumper will surely some time talk to a hiker) can become friends of yours.

And then yes, internet. Also makes you a lot of potential acquaintances or friends. You can be a modern jester or a electronics hobbist that puts video on youtube or you can make furry porn regularly, you'll quite possibly get in contact with people as long as you do it regularly.
Even if you play random video games or whatever else, you will. Shit, I had a lot of opportunities to make friends in my srs gaming phase... though of course I only met a few multiple times IRL, their and my travel expenses are an issue in these cases.
