A lot of it is like once you have "a thing" like al algorithm that describes a tube for example, it's a lot easier to just use that again and again and it takes so much less time than making a whole new thing - like you make one VCA compressor and the next 5 are 90% done already. SO as we get more and more "components" like preamps, transformers, eq, whatevers, it opens up more and more lower-effort things. Like dolby is basically just an eq in front of a preamp and then another eq after it etc etc. It's like building a bigger and bigger collection of legos in some ways. It's also why I will probably never end up doing anything super unique or revolutionary... all this stuff is stuff other people figured out a long time ago and we're just translating it.
