I agree. What most HN commenters seem to really mean when they say "technology" is "consumer software", or more cynically, "company is made of mostly software engineers".
There is an incredible amount of advanced technology being created and used by more "traditional" industries like manufacturing, aerospace, or animation.
Why should Facebook be considered a technology company but not Pixar, Ratheon, General Dynamics, Corning or TSMC? It makes zero sense and relies on a very self-serving definition of "technology".
