If you've ever had to figure out a weird behavior that was ultimately the result of unsiloed apps just hanging out in each other's data, or had to deal with an uncontrolled Smalltalk object soup, you'll have strong opinions on this idea. They are not positive. All these environments went away for a reason, and it wasn't their indubitable supremacy. They were great for solo devs, but they break down at a larger scale. (Often, not always, you can find counterexamples, but, again, the market has judged) And given that we can't even really decide on decent data format for dates (https://en.wikipedia.org/wiki/List_of_date_formats_by_country https://en.wikipedia.org/wiki/List_of_date_formats_by_countr...), the view that composability were easy if we just were less siloed is, at best, naive. Even if we managed to somehow achieve it without making a giant code mess.
