The 2/3 citizen problem is everywhere in tech. Look out for it and avoid if you can. It is probably an innovation token. That is why I am less enthusiastic about things like Supabase (picking on the one I remember) and it’s ilk over just Postgres.
Maybe I am waffling on the basic point of: boring is good, at least as a default to be convinced from.
I've worked at companies that have had bare metal DX and they used it to stab themselves. I mean, anyone can be contrarian, and that's not what I'm trying to do here, but there is value in "idk what the queue is or how it's implemented, but I know how to call it". If you're not using an abstraction layer for everyday engineers (on a project that has 20+ engineers on it), then that means either your building one yourself, or you're forcing your teammates to engage with DevOps themselves.
If I were to start a company from scratch, I'd use something like encore.dev, because even though there's a framework to learn, it's a DevOps-less, or less-DevOps approach to building software fast without boilerplate.
And I'm not sure what it is about express.js, but everyone seems to have their own way of doing it. It's cool to see paradigms solidify, like tRPC and Nest.js, and now this.
Where is the value that when your devs push something that breaks, you need to rely on external people to un-break it?
It's a business model, it only gives value to the company that build the framework. It only gives debt to the people using it...
That said, if they stay in baby form and never grow...
It wasn't all that long ago that it would be unusual for a programmer to not understand assembly code - and before that, to have an understanding of how transistors/vacuum tubes are assembled to make complex circuits.
But of course, nowadays for web development everybody trusts the CPU architecture to operate efficiently, the OS to do reasonable things, TCP/IP to remain reliable, browsers to support Javascript, etc etc. In the last few years we've even seen some stabilization even around the historically churny realm of javascript UI libraries - most developers don't even need to know how React works under the hood, let alone how V8 runs.
The reasonable level of abstraction has grown immensely, and the number of web developers who deeply understand the true stack is probably fewer than 10. For most use cases, a service that abstracts over the various cloud provider options is perfectly fine - and when its not, that's generally a "good problem" to have (because it means your app is having scale issues).
All business models are meant to give value to the business. The successful ones also give value to the customers.
