Now that word no longer refers to a profession but to a machine

For instance, we no longer teach taking square roots by hand in schools or calculating OLS regressions by hand in universities because computers now do those.

Instead, we focus on understanding the underlying concepts.

Likewise, the field of accounting needs to radically change.

To be sure, I didn’t call for eliminating teaching all activities that AI can also do.

You’re correct that using and evaluating AI’s capabilities are increasingly important skills. That can require *deeper* understanding.

But, in turn that’s a sign it requires rethinking teaching and work.
