When you make a claim such as "this change won't introduce any
regressions" the evidence of "it works in my machine" isn't *proof* of
any kind. If you have worked in any serious project you would know
that (as many changes work on particular machines, and break in
others). And if you know anything of the scientific process you would
also know that "it works in my machine" isn't *proof* of any kind; my
machine detects neutrinos travel faster than light, is that proof of
anything? No. And this goes back to basics of rationality: you can't
prove a negative, so it doesn't matter how many data-points of
something not happening you have, and all you need is a positive
data-point to show that something does indeed exist (or at least it's
as likely as the possibility of that data-point being in fact true).

I'm not going to explain this again. Either you get it or you don't.

Cheers.
