There was a civilian airplane that mistakenly drifted into Soviet airspace and was shot down back in the 1983, killing everyone on board. Pilots can train for scenarios requiring manual operation, but that doesn’t mean they should only rely on human perception, especially when it involves other people’s lives.
Internet of the 90s and early 2000s were introduced as a library where people consulted text for information. There was an introduction (tutorials), a userbase that’s educated and/or eager to learn, and most importantly, it was the wild west where companies didn’t think much of except for just having a .com address.

For people who were born after smartphones and grew up without knowing the early stuff, the search engine is… well, do people know or even care about that?
