As I recall, there was some, but not a lot of FUD around spellcheckers, mostly because personal computers were still relatively new. Most GenX parents (Boomers) didn't even know what personal computers were yet, so they didn't know enough to be concerned. (I grew up in Missouri, which was the Digital Stone Age back then.) At the time, I think their complaining was more focused on MTV and video games.

However, also sounds weird, but I recall myself and some of my peers questioning spellcheckers, "Why do I need this?", because spelling was a primary mission of our education. We were all raised constantly being tested on spelling. In fact, I think I disabled the spellchecker on my old-ass 286 because it caused delays in the overall experience.
