I'm not sure why you say the analogy fails just because general AI has more applications than excavators. A tool is still a tool, regardless of how much human effort it replaces.
"Calculator" used to be a job title. Now it's a machine. In the same way, "construction worker" may one day be a machine. "Software engineer" may one day be a machine. "Engineer" in general may one day be a machine. This forum seems to think that if humans are not required to think hard about existing problem domains, something terrible will happen.
At the end of the AI revolution, thinking may become something like physical exercise -- something we do because it's fun, and keeps us healthy and attractive, not because it's required.
To be clear, I do think that AI poses a potential risk to humanity. But imo "we won't have to think as hard" is not a risk; it's a benefit.
