We can spent more times discussing this, but let's fe real here, who expected bitcoin to be created? I found out for this year ago, and before that I didn't even think about something like this can happen.
It's just that anything can happen, I believe in bitcoin don't understand me wrong, I believe bitcoin will last a long time, but I'm opened for new things, and who knows what will happen in 50 years from now, this technology is changing everything each year. In some moments it's very hard to follow that progress, even harder to predict far future.
