My theory: The "long S" in "Congreſs" is an f. They used f instead of s because without modern dental care, a lot of people in the 1600's and 1700's were miffing teeth and fpoke with a lifp.

That’s not the case.

You should tell ChatGPT your theory, then maybe you'll find someone that thinks it's worthwhile.
