Re: General Anime Discussion Thread
Harry did an article a few months ago where he discuss this. What he said was that because the people in the Pokemon World relied on Pokemon so much that technology that isn't related to it never developed as it does in our world. So things like Airplanes are not the same as ours because trainers could simply just grab a Fearow and Fly to the next city.
I am guessing the same can be said in the anime. The only difference is that it changes from regions to regions. I do remember that Ash, his mom and Oak flew on a plane to get to Unova though. It looked a bit old fashion though.
