There's a particular dubious point: equivocating simple systems with stable systems. The paragraph about Instagram looks plainly wrong to me, about sticking to "battle-proven and easy-to-understand PostgreSQL and Redis". PostgreSQL is certainly not simple nor easy to understand. And Redis was not much "battle-proven" in 2012, just 3 years after its first release. It's even funny to oppose them to "NoSQL data-stores", since Redis is a NoSQL key-value store.
I have started to realize that so much in our society is how it is because we need some kind of consensus to move forward. And so much of added complexity exists because there are no good consensus.
Think about OS portability for example. If we had consensus on the OS APIs then there would be no cost to portability at all almost. But it is a complex thing and hard to get consensus on so we can't have things that is compiled towards an ISA and then runs everywhere. If something is super simple then it will be easier to make a consensus among people that it should be adopted.
But this also connects to the topic of this article, if it is easy to create a consensus among others about it that might be bad for business. That will make it super easy to compete with you. And make it harder for you to sell it (it is hard to figure out how to monetize open source).
From wikipedia:
Solomon Hykes, a co-founder of Docker, wrote in 2019, "If WASM+WASI existed in 2008, we wouldn't have needed to create Docker. That's how important it is. WebAssembly on the server is the future of computing." Wasmer, out in version 1.0, provides "software containerization, we create universal binaries that work anywhere without modification, including operating systems like Linux, macOS, Windows, and web browsers. Wasm automatically sandboxes applications by default for secure execution".
Aren’t most complex solutions just a recursive version of this strategy? I don’t hate this idea, in fact I often love this idea but it can more often than not pathologize into not invented here or the xkcd standards meme.
