It isn't that technology has changed humanity, it is that we're all very much the products of our environment. The founding fathers lived in an era where slavery was common, women couldn't vote, and where the US was a new country finding it's way in the world.
The system they put into place does not directly protect against tyranny: what it does instead is protect the status quo. The system they set up instituted it's own hard-to-change tyrannies, by doing things like not giving women the vote and by not recognizing all people as equal, but sure, the relatively blank slate they had made it significantly less likely that there'd ever be a dictatorship of any kind in the US. Now, though, there's over 300 years of laws on the books that are being protected by the system they put in place and rather than "slow down the leviathan" they ensure it remains in place, warts and all.
