Then you got bipolar junction transistors (BJTs), and most digital logic, such as ECL and TTL, was based on a different paradigm for a few decades.
Then came the MOS revolution, allowing for large scale integration. And it worked like relays used to, but Shannon's work was mostly forgotten by then.
I think the emphasis is misplaced here. It is true that a single BJT, when considered as a three terminal device, does not operate in the same “gated” way as a relay and a CMOS gate does.
But the BJT components still were integrated into chips, or assembled into standard design blocks that implemented recognizable Boolean operations, and synthesis of desired logical functions would use tools like Karnaugh maps that were (as I understand it) outgrowths of Shannon’s approach.
This is my candidate for the sickest burn in a mathematical journal paper...
Tho I’m intrigued by the idea that there’s more to information than Shannon. Any additional hints??
I’ve often thought about a dual metric with entropy called ‘organization’ that doesn’t Measure disorder/surprise, but measures structure, Coherence. But I don’t think it’s exactly a dual.
