So instead of using their time on something important, they're chasing after proof of some stupid idea that reality's just a computer simulation? Give me a break. I honestly don't see why it matters whether reality's real or not. It feels real so I don't care and I think a significant portion of other people would feel the same way.
to be fair many of these "stupid" ideas and research bare out many results that while not doing anything for the research they came from end up advancing other more non"stupid" research projects. A lot of modern scince is part planed research and part unattended side effects of planed research that failed.
