I’ve been using Sonnet 3.5 to code and I’ve managed to build multiple full fledged apps, including paid ones
Maybe they’re not perfect, but they work and I’ve had no complaints yet. They might not scale to become the next Facebook, but not everything has to scale
Do you think you could you maintain and/or debug someone else's application?
In fact, my main reason for not doing any web development is that I find the amount of layers of abstraction and needless complexity for something that should really be simple quite deterring.
I'm sure e.g. React and GraphQL allow people to think about web apps in really elegant and scalable ways, but the learning curve is just way more than I can justify for a side project or a one-off thing at work that will never have more than two or three users opening it once every few months.
