No, it wouldn't; in fact, the false vacuum hypothesis makes it worse.
If this hypothesis is true, it means that there were no technological
civilizations in our galaxy until extremely recently: at most 50,000
years or so.
Actually, I think that this is a pretty good argument against the
hypothesis that we're living in a false vacuum and that it's
easy to induce a phase transition. If it were that easy, then
someone else would probably have done it by now.
(But I admit that I get a kick out of imagining protests outside the
construction site of the next major accelerator, with protesters
waving "SAVE THE UNIVERSE" banners.)
