Adding "techno-" to a failed system does not magically make it work.
Isn't this sort of what Washington and those colonial fruits did with the democracy of the ancient greeks/romans? But I'll give this to you: If that's the case, it sure is NOT very reassuring.
This was not a techno-republic. (Side note, you said democracy, which is wrong, the founder rejected that system intentionally.)
The founders were keenly aware that they were making a temporary thing. They were all serious students of history, and they knew damn well how and why Republics died. From Athens and Sparta through Rome to Vienna, they knew that every Republic eventually commits suicide. The collapse of the Venetian Republic was an ongoing event while they were drafting the Declaration of Independence and the Constitution, and it was well known to the founders.
They still thought it was the best option, and plenty of us still agree today. Some of us even stick around watching the suicide in progress, saying "Not today!".
