I don't think this logic applies to software development in general and algorithms in particular.

When you need to roll out a b-tree from scratch, just crack open a book and read up. The worst thing it can happen is that somr acceptance test fails and you roll back a change. That is hardly a life-or-death scenario.

The word "soft" in "software" has meaning.

Gp's point is about how there are many things worth learning even if you can't immediately see how they will be useful, and not about urgency or timing. Sure you can pick up a book and learn about b-trees if you have to but you might not even know that a b-tree is what you need in a particular problem if you never learnt it in the first place. Most algorithmic problems in the wild don't present themselves cleanly with a signpost saying 'this is an X algorithm problem'

How would you know you need to use (or implement) a B-Tree in your solution VS some other data structure?

Realistically, do most pilots remember these things?

I also don’t understand the career claim. How does that work?

Yes, as they’re literally life-and-death in many cases. Getting a pilot license requires one to demonstrate the ability to do certain “not common but not exactly uncommon either” recovery things from memory. And different bits of those “1000 things” play a role in different scenarios. If you’re lucky and at high enough altitude to have time to look up a checklist in the POH it’s great. When you have seconds because you just took off or something screws up on final you don’t have time to go through the POH or futz around with the checklists in your avionics (if they’re even there).

The pilots that don’t remember these things when they’re needed are dead.

> Developers who have an understanding of the how -and- why when they are required to solve a problem vs just plugging a library in will have a much better career developing solutions and leading teams that do exceptional work.

Will they? Or do you just like the idea of a world where that is true?

Programming is (almost) never life or death and honestly is rarely even in the same ballpark.

Most people don’t need (or want) to do exceptional work.
