Less pithily, the good architecture will almost certainly end up with arbitrary patches and madness after 2 years of active use, if anyone cares about it at all... And then somebody will join and say 'This is a mess, we should refactor and/or burn it to the ground.'
While true, in my experience this usually happened when at least one - if not all three - of these conditions were true:
1. The problem domain is relatively static, unmoving, and self contained
2. The systems in question is relatively small
3. The developers in question have written substantially similar systems before, or ground locally, or used version 0.x version numbers first (in any of these cases, is it really "version 1" per se?)
...game development is admittedly weak in all 3 categories, and high on time pressure. Oh sure, there's some solid code that will probably last decades in many codebases, but even the best programmers will occasionally make a system that - while good in isolation - needs reworking when combined with other systems - to say nothing of the content and rendering pipelines that vary wildly by decade.
Caveat: it's never something that's too large or complex, of course.
I've known several such systems, and the reason they stuck with the original architecture is they wrote it in C, and it's very hard to iterate architecture in C programs. The programmers will just keep bashing the C code so it works well enough.
Yes, I know this is a provocative statement.
The reason behind it is that C's ability to encapsulate behavior is just not very good. Even simple things, like "is it an array or a linked list" leak out all over the place.
Even simpler, "is it a value or a reference type" means one has to swap "." and "->" everywhere. C++ half-fixed it by introducing reference types, D fixes it all the way by noting that "." can be unambiguously used for both operations.
Design a system to be modular from the very beginning with only the most fundamental of API signatures and you win. Many of these signatures may even no-op for years, but because they're fundamental to the problem, you know there could be a case where they're needed.
I've never had a failed or late project and most of my projects are ones that were assigned to me because no other team would touch them due to all of the attention and required SLAs.
Probably one huge confounding factor, however, is the continual drive by juniors (or supposed seniors who think like juniors) to use the latest & shiniest technologies. These of course these are unknown to the team, of questionable long-term suitability and introduced without knowledge of the "right" way to use them.
In the article the OP describes using Elixir without A) needing it or B) being able to handle its downsides. Plus many random versions of Angular and React. Plus the overheads of an excessive focus on SOA.
My emphasis in architecture is on using simple & strong tools, and delivering great architecture in the problem space. Configurability, extensibility and DSLs are my forte. I don't need a new language -- I know how to use the ones I've got.
