Great video and topic!
I cringe every time I hear someone refer to computers & electronics as "Technology." Heck, technology has been around as long as man. It's all around us, and is not limited to modern electronic devices or gadgets at all for that matter. The alphabet was technology that eventually led to the ballpoint pen and pencil. Now we use email and Internet forums to communicate. The invention of the wheel was technology that led to driving on paved roads instead of dirt roads.
Grilling/smoking/cooking technology is no different and has changed a lot. Pellet grills just happen to be an extension of that ever changing technology.
