Everything to agree with this article. I personally find it sad that a lot of people will still defend current state of software because "features". Like the author I feel same disenchantment as microservice/devops/cloud evangelist keep telling me how my old services need to done from scratch with 3 more layers of abstraction to become state of the art.
Abstraction isn't the reason code is slow. Reducing abstraction is an utter micro optimization. The idea that abstraction has to give way to performance is a fallacy in most cases.
The reason software is slow is because people write shit code, with or without abstractions. Too much db/api traffic, suboptimal algorithms etc. Fact is, most developers just suck at programming. Which makes a lot of sense at least where I am because we don't have any rigor in our craft. People go through a bachelor's degree learning as little as possible and the bar for passing is embarrassingly low. They get a job and the employer just puts them to work, personally I was placed alone on a maintenance project for a large application. Nobody reviewing my code, nobody else with any sort of domain knowledge to lean on.
In other professions, people have apprenticeships and such where experienced peers teach them the things they need to know and make sure they do things right. In software nobody gives a shit. Some QA person goes into the app and clicks a button and if it seems like it works they ship it.
People are stacking shit on top of shit, literally just writing legacy code. Because nobody teaches people how to do things right and nobody checks their work to see if they have done things right.
