Even if they can use tools, they should know de basics. Engineers are teached calculus even when there are tools that can do it much better and faster.

Knowing the basic of argument making will help them choose a good tool vs. a bad tool. Help them realise if the tool is failing, somehow, like changing their main directive. And finally, if you know the basics, you can use that tool better.

For example, someone good at math will know how to use a calculator effectively. If you give them a paragraph, they would know which equation they need to formulate to get the right answer. Someone who doesn't know is only able to insert te equation if directly given to them, and not just implied in a paragraph.
