Riding a bike is real. Catching pikachu is not real, but since it takes place in the real world it has real consequences. If a bunch of Pokemon ran off a cliff would you follow them? That is just one question this social experiment seeks to answer.
The lines are definitely being blurred.
It would be pretty easy to argue that if you ride a bike in a big circle, right back to where you started, that you have accomplished less than by ‘capturing’ some bunch of electrons. Some people highly value the warm fuzzy feeling they get by knowing they rode their bike... nowhere. But hey, they feel like they accomplished something. Same with the Pokémon catchers. They feel like they accomplished something but someone else could argue they wasted their time. Everyone wants to feel like they accomplished something. Some think mocking others on the internet is accomplishing something. Some even thing that is more than catching some electrons. Others might disagree.
