It doesn't say how an effective, efficient, nor industrial low-lantency engine works, nor what a microsecond level engine is (insofar as a label cutoff).
Honestly, boring heap/stack practices with mindfulness about the application workflow and memory management therein goes miles.
I wonder how much of it is them trying to minmax their revenue generating marketing algos for content discovery. (Willing to bet it's somewhat relative)
I have been building my own game and game engine for a while now, and cannot help but see whats really happening with vibe coded game generation: and investment into the content generation pipeline.
I feel a solid game engine paired with a good content pipeline can ship games at such a rapid clup that the gameslop gets lost as the noise it is.
If you star changing the term slop into meaning content someone made that you don't like, you begin to diminish the word, and also who are you to categorically dismiss a stranger's work for someone else? Not good form.
So good
