Those who claim that their product is the greatest thing since sliced bread (which ironically itself wasn't the "greatest thing since sliced bread" at first) sometimes might be delusional or even just lying. I'd take an honest product that provably helps people over a mere pipe dream any day. That's not to say that a visionary product doesn't have appeal or can't be truly world-changing but chances are that you'll make a far greater impact in changing the world by taking small, incremental steps.
