Nah, I'd say that common "americans" (really: US citizens) are perhaps a bit on the dumber site. Not only confuse they constantly a continent (America) with a country (USA), they also have no idea about history. Or logics. You wrote "ALL of tech" ... no lets check.

Cars - Germany (Gottlieb Daimler, but he didn't patent it), Germany (Carl Benz which made the first patent).

Motorbikes - Germany (Gottlieb Daimler)

Train - invented in Germany

Radio transmission - UK (James Clark Maxwell described them theoretically), Germany (Heinrich Hertz created/used them first in experiments)

X-Ray - Germany (Gustav Röntgen)

Telephone - Germany (Philipp Reis, your Bell bought examples and reverse engineered them)

Bookpress with movable letters - Germany (Johannes Gensfleisch a.k.a. Gutenberg)

Lightbulb - Germany (Heinrich Göbel)

Periodic system of elements - Russia (Dimitri Mendelejew) and Germany (Justus Lothar Meyer)

Dynamo / Generator - Germany (Werner von Siemens)

Vaccination - UK (Edward Jenner)

Gliding plane - Germany (Otto Lilienthal)

Pain killer - Germany (Felix Hoffmann, Aspirin)

Relativity theory, Quantum theory - Albert Einstein, Planck,

TV - Germany (Manfred von Ardenne)

Cathod ray tube in TVs - Germany (Conrad Röntgen experimentally, Ferdinand Braun with horizontal and vertical directivity of the ray)

Computer - France (Charles Babbage, Ada Lovelace) for mechanical ones and Germany (Konrad Zuse) for electric ones

Atomic fissure, used in plants and bombs - Germany (Otto Hahn)

Chip cards - Germany (Jürgen Dethloff, Helmut Gröttrup)

MP3 music compression - Germany (Fraunhofer Institut)

Electricity - actually already in ancient greek they used electrostatic charging of amber. And one century before Christ they had actual batteries in Bagdad! But then a plethorary of european scientists brought the work forward: UK (William Gilbert, Francis Hauksbee, Joseph Priestley, Henry Cavendish, Humphry Davy, Michael Faraday), Germany (Otto von Guericke, Ewald Jürgen Georg von Kleist, Georg Simon Ohm, Carl Friedrich Gauß), Italy (Luigi Galvani, Allesandro Volta), France (Charles du Fay, Charles Augustin de Coulomb, André-Marie Ampère), Netherlands (Pieter van Musschenbroek), Denmark (Hans Christian Ørsted).

I actually terminate this electricity list here. I could go on and on.

Also note that physical units named after their discoverer indicate some kind of importance of the relevant invention. So we have e.g. Volt, Ampere, Coulomb, Farad, Gauss, Watt, Ørsted, Tesla, Weber as units. None of them is based on USA's academia.

If we look at unit names outside of electricity we also find outdated ones like Röntgen or Curie. And still used ones like Plack constant, Newton, Pascal, Kelvin, Becquerel, Gray, Sievert. So where are the USA american ones if "all" of technology is supposed to stem from their academia?

IF we want to trace the roots, then perhaps we need to go back to antique greek philisophers. Because western academia itself traces itself there. But then again ... something like that existed also in ancient India and maybe China.
