I agree. It's engineering. There's a difference between launching a spacecraft and use it to do something no one has done before and building a 50km long bridge. Both are incredibly hard and expensive, but one of them is "only" engineering, the other has science as well.

There's no such thing as working in "tech". You are always working in "tech", whether it is using Excel or WebGL. When newspapers call the latter "tech", what they really mean is "new tech".

Programming a 3D multiplayer game in a browser is a re-combination of existing technologies, and therefore not "new tech". (Though of course, new, compared to Excel, but only by a few years.)

It sure as hell is. You have just chosen a definition of technology that differs from the rest of the world.
