I think there are some physical problems trying to brute force a 12 word phrase. Afaik, 12 words equals 10^39 possibilities. From the discussion about energy use of calculations (especially regarding bitcoin mining), I think to remember that doing 10^20 calculations per year costs about as much energy as an average country consumes. If those numbers are correct, it would take 10^19 years to break a 12 word phrase if you apply the energy budget of a whole country to it. 10^19 years is something like a hundred million times longer than the universe has existed.
