Some software bloat is OK

The "development time is more important than performance" motto treats bad performance as the problem with software, when in reality poor performance is a symptom of growing software complexity. I'm sure that each individual coder who has contributed to software bloat believed that their addition was reasonable. I'm sure everyone who has advocated for microservices fully believes they are solving a real-world problem. The issue is that we don't treat complexity as a problem in-and-of-itself.

In physical disciplines, like mechanical engineering, civil engineering, or even industrial design, there is a natural push towards simplicity. Each new revision is slimmer & more unified–more beautiful because it gets closer to being a perfect object that does exactly what it needs to do, and nothing extra. But in software, possibly because it's difficult to see into a computer, we don't have the drive for simplicity. Each new LLVM binary is bigger than the last, each new HTML spec longer, each new JavaScript framework more abstract, each new Windows revision more bloated.

The result is that it's hard to do basic things. It's hard to draw to the screen manually because the graphics standards have grown so complicated & splintered. So you build a web app, but it's hard to do that from scratch because the pure JS DOM APIs aren't designed for app design. So you adopt a framework, which itself is buried under years of cruft and legacy decisions. This is the situation in many areas of computer science–abstractions on top of abstractions and within abstractions, like some complexity fractal from hell. Yes, each layer fixes a problem. But all together, they create a new problem. Some software bloat is OK, but all software bloat is bad.

Security, accessibility, and robustness are great goals, but if we want to build great software, we can't just tack these features on. We need to solve the difficult problem of fitting in these requirements without making the software much more complex. As engineers, we need to build a culture around being disciplined about simplicity. As humans, we need to support engineering efforts that aren't bogged down by corporate politics.

We do see the same in physical engineering too. At some point some products have plateaued, there's no more development. But still you need to sell more, the designers need to get paid and they are used as status symbols and so on.

One example is skirt length. You have fashion and the only thing about it is change. If everybody's wearing short skirts, then longer skirts will need to be launched in fashion magazines and manufactured and sent to shops in order to sell more. The actual products have not functionally changed in centuries.

Or people just start ignoring the trends and only replace their clothes when they wear out.

I don't think that fashion trends are comparable. I think that fashion trends are fine in concept–things get old and we switch things up. It's the way the human superorganism is able to evolve new ideas. Unfortunately, capitalism accelerates these changes to an unreasonable pace, but even in Star Trek communism, people get bored. The cultural energy that birthed one style is no longer present, we always need something new that appeals to the current time.

But clothes still have to look nice. Fashion designers have a motivation to make clothes that serve their purpose elegantly. Inelegance would be adding metal rails to a skirt so that you could extend its length at will. Sure, the new object has a new function, and its designer might feel clever, but it is uglier. But ugly software and beautiful software often look the same. So software trends end up being ugly, because no one involved had an eye for beauty.
