Offhand, it just sounds like you're a giant jealous peckerwood because you can't have something some of us can. I need an assisted/auto like I need an AR. I don't need it, I want it. I see absolutely no downside to an assisted knife. I carried one for years. There may be downsides to an auto, depends on who you are and the uses you have for it.
But I will tell you this; I'm not fond of thumb studs. For some reason I can't understand, I have a hard time with them. Every time I try one, I come close to separating a fingernail from the nailbed, which is never a good time. So I get that lots of people like them, that's cool, they can have my share. I'll stick to autos, thanks.
