That's my entire industry, so I can believe it. I'd love to learn large scale game architecture but it simply isn't public. At best you can dig into the source available 30 year legacy code of Unreal Engine as a base. But extracting architecture from the source is like looking at a building without a schematic.
Your best bet is a 500 dollar GDC vault that offers relative scraps of a schematic and making your own from those experiences.
Have you seen the presentation from GDC 2017 on the architecture of Overwatch [0]? If you watch the video in detail -- stepping through frame-by-frame at some points -- it provides a nearly complete schematic of the game's architecture. That's probably why the video has since been made unlisted.
Jell-o (gello?) is a good example, nothing tastes like it naturally. Why aren't there tasty food that are original in terms of taste and texture but good for health and the environment? I suppose part of the struggle is that food is entrenched into culture so much. burgers and bbq are inextricable from july 4th and memorial day for example.
Do you mean processing ingredients with the goal to take cheap ingredients and make a product as hyper-palatable as possible? That would generally be called "ultra-processed food"; you're not going to find a Doritos chip in nature.
Do you mean developing completely completely new flavors via chemical synthesis? I don't think there's much possibility there. Our senses have evolved to detect compounds found in nature, so it's unlikely a synthetic compound can produce a flavor completely unlike anything found in nature.
Also, I think you're overestimating jelly. Gelatine is just a breakdown product of collagen. Boil animal connective tissue, purify the gelatine, add sugar and flavoring and set it into a gel. It's really only a few of techniques removed from nature. If you want to say it's not found in nature, then fair enough, but neither is a medium-rare steak.
