I've had a thought bubbling away lately, informed by AI hype, some job market research, the "enshittification" book/topic doing the rounds, and I guess lived experience too.
Computers were invented, and initially used for calculations, punch cards, databases, spreadsheets, automating warehouses and running airlines and stuff. Computers are really good for that stuff, like many orders of magnitude better than analog alternatives.
Later, computers became a mass market consumer product, and we had the web and internet, and moving everything online became a fad, much like AI is a fad now. This pushed computers into some fairly marginal use cases, like "social media", publishing, messaging, e-commerce, and CRUD apps to manage workflows like JIRA and friends. Computers are kind of ok for this stuff... but, frankly, not that much better than the original thing. Like, a telephone, fax, etc. already allowed instant communication, email is maybe a bit better than fax, but it's not 1000x better. JIRA is a bit better than a whiteboard and post-it notes, but, also probably not 1000x better.
It's these recent, marginal-ish use cases that are getting destroyed by enshittification, AI, etc... because they were just never that good an application for computers and UIs in the first place. I think, if one wants to work on, or use an application that doesn't get filled with ads or have a copilot gratuitously inserted or whatever, it's probably more likely to happen in software for fluid dynamics or some natural fit for using a computer. Conversely, anything like facebook or jira or whatever that never really needed to be a computer app apart from because it was fashionable... is now unfashionable.
