My gut reaction is that the article is nonsense but I think there's a very valuable point in it.

When you work mainly on enterprise code where you're unlikely to encounter any code you wrote, rather than another team member, on a daily basis you'll need a debugger or print statements.

But the reasonable point the article makes is a debugger makes it very easy to solve the problem localised to a function or a couple of lines of code rather than take the time to improve the whole area and/or add test coverage. But the other thing people who don't work on enterprise code won't necessarily understand is you don't usually have time to do that. So it's a good thing to keep in mind but it feels a little too Ivory Tower to be broadly applicable.
