This was an attempt to prevent this exact chain of response.

I calculator can only be used indirectly to solve a practical problem. A more general intelligence is required to know a calculator is needed, and how to break down the problem in a way that a calculator can be used effectively.

For example, you can't solve any real world problem with a calculator, beyond holding some papers down, or maybe keeping a door open. But, an engineer (or other general intelligence) with a calculator can solve real world problems with it. Tools vs tool users. The user is the general bit, not the specific tool that's useless on its own!

I think we've reached the limits of communication. Cheers!
