Technology concern

[MrBin]

(Bad engrish ahead)
In a shared reality like this, isn't like I could just make something float because we all are accostumed to Gravity's action; instead, most of what I seen (and experimented?) involves affecting the random, correct?

I don't yet know about quantum computing nor its implications, though if technology doesn't yet look scary enough, my biggest concern is that no system truly applies the random, they rather simulate it, through the same accuracy as everything else. This goes for PCs, mobile phones, gaming consoles, web servers and so on; any internal discrepancy would crash the system almost immediately. Just overclock your PC a little too much and you'll guarantee a kernel panic or bsod within minutes unless you upgraded the cooling.

Wouldn't it make the Law of Attraction much harder to apply in an era like this?

EDIT: Interesting but probably unrelated, I remember my mom said that "witchcraft" was still frowned upon in this country as late as the 90s (and we still have laws against it), and it appears they stopped caring from ~2000s onwards.
