Personally I found the definition of a game engine as
```
while True:
update_state()
draw_frame()```
To be a profound concept. The implementation details are significant. But establishing the framework behind what we’re actually talking about is very important.
How you go from "smart people should reproduce more" to "cull the population of the unfavorable" is on you, but thats certainly not the conclusion I would draw.
If someone told me it was pure CSS, I'd believe them. I'm not a frontend dev, so I'm always impressed by what you can now do without having to import a whole JS library.
