Using technical language suggests to readers that the author is responsible for creating the complicated inventions being described.

Using technical language helps the author stress the complexity of the scientific advances and technological achievements that Edison observed.

Using technical language allows the author to obscure the fact that much of what Edison observed was ordinary, unimpressive, and commonplace.
