Why does the author's description of what Edison observed during his visit to the laboratory—"the 20-kilowatt Langmuir amplifying electrotubes, which have superseded the Alexanderou alternator in long distance radio broadcasting"—intentionally incorporate such highly technical language?

Using technical language helps the author stress the complexity of the scientific advances and technological achievements that Edison observed.
Using technical language lets the author share controversial information in ways that most readers will not fully grasp or understand.
Using technical language allows the author to obscure the fact that much of what Edison observed was ordinary, unimpressive, and commonplace.
Using technical language suggests to readers that the author is responsible for creating the complicated inventions being described.
