Cognitive load is what matters

I'm probably one of the "smart developers" with quirks. I try to build abstractions.

I'm both bothered and intrigued by the industry returning to, what I call, "pile-of-if-statements architecture". It's really easy to think it's simple, and it's really easy to think you understand, and it's really easy to close your assigned Jira tickets; so I understand why people like it.

People get assigned a task, they look around and find a few places they think are related, then add some if-statements to the pile. Then they test; if the tests fail they add a few more if-statements. Eventually they send it to QA; if QA finds a problem, another quick if-statement will solve the problem. It's released to production, and it works for a high enough percentage of cases that the failure cases don't come to your attention. There's approximately 0% chance the code is actually correct. You just add if-statements until you asymptotically approach correctness. If you accidentally leak the personal data of millions of people, you wont be held responsible, and the cognitive load is always low.

But the thing is... I'm not sure there's a better alternative.

You can create a fancy abstraction and use a fancy architecture, but I'm not sure this actually increases the odds of the code being correct.

Especially in corporate environments--you cannot build a beautiful abstraction in most corporate environments because the owners of the business logic do not treat the business logic with enough care.

"A single order ships to a single address, keep it simple, build it, oh actually, a salesman promised a big customer, so now we need to make it so a single order can ship to multiple addresses"--you've heard something like this before, haven't you?

You can't build careful bug-free abstractions in corporate environments.

So, is pile-of-if-statements the best we can do for business software?

> So, is pile-of-if-statements the best we can do for business software?

I'm not sure if that's anywhere in the rating of quality of business software. Things that matter:

1. How fast can I or someone else change it next time to fulfill the next requirements?

2. How often does it fail?

3. How much money does the code save or generate by existing.

Good architecture can affect 1 and 2 in some circumstances but not every time and most likely not forever at the rate people are starting to produce LLM garbage code. At some point we'll just compile English directly into bytecode and so architecture will matter even less. And obviously #3 matters by far the most.

It's obviously a shame for whoever appreciates the actual art / craft of building software, but that isn't really a thing that matters in business software anyway, at least for the people paying our salaries (or to the users of the software).
