Agree that this kind of incompetence exists in all sectors and I think we don't talk about it, it becomes acceptable. We're not trying to blame a single developer, that'd be inappropriate. But, the management and QA culture in a AAA game studio that rakes billions ought to be better.
The complexity is in reverse engineering the binary. The developer has access to the full source code and the profiling tools I presume.
Another one is in Microsoft Flight Simulator, instead of downloading multiple archives, it downloads one, unzips it using a single CPU core and then downloads another one. MSFS 2020 takes a few hours to install and that's not just because of the internet connection, but this shitty installation code.
2. this kind of incompetence exists in all other sectors. That's why pentests are so crucial, and why they guard the security of millions.
3. we'll have to agree to disagree that it's a minor miracle. Having seen the complexity firsthand, it's quite amazing.
