I prefer the adage; as simple as possible but no simpler.
Some ideas are not easily communicated because the shared language does not provide the right constructs for it. I.e. incommensurable.
In assuming that I’m not the first nor the smartest person to approach a problem, it’s likely that someone else smarter found something useful and wrote it down in terms that I do not understand. So I built a cross domain search engine and used it to find the solutions I was after in other domains of expertise. I was then able to combine several the found solution components into a whole working solution. I used to work in search, so that was something I already knew how to do.
I’m sure we could stop inventing new things and coast for a long time by simply digging up old ideas instead of wastefully reinventing them in new domains. But people like new things... so we’re back to the people problem.
