While all that would be cool and all, we already have something which gives you all of that, its called memory. The stronger your brain is the more memory you can hold in your brain and the better it is revealed to you. But following your idea, if you've invented a gadget like that then you know time travel has been invented. Could you imagine how fucking complicated that would be? And in how many different fucking dimensions your brain would be in or some shit like that. Like you could search a memory, then go to the time of that memory, change the events and then when you got back to present time your brain gadget still held the way it happened first and you stumpled upon the memory and you learned something new about yourself or something. I'm fucking STONED OFF MY ASS!! LMAO. God damn. Anyway, enough rambling. Sorry guys, didn't mean to make the post this long.
