Sometimes it might, if there are security implications. You might need to fix bugs in networking code, or update crypto handling, or whatever, and those types of things are fine. The idea that you can't have legitimately useful one-off software, used by millions, despite not being updated, is a silly artifact of the MBA takeover of big tech.
Continuous development is not intrinsic to the "goodness" of software. Sometimes it's a big disappointment if software hasn't been updated consistently, but other times, it just doesnt matter. I've got scripts, little apps, tools, things that I've used, sometimes daily, for over a decade, that never ever ever get updated, and I'd be annoyed if I had to. They have simple tasks to perform that they do well; you dont need all the rest of the "and now we have liquid glass icons! oh, and mandatory telemetry, and if you want ads to go away, you must pay for a premium subscription"
The value is in the utility - the work done by the software. How much effort and maintenance goes into creating it often has nothing to do with how useful it is.
Look at windows 11 - hundreds of billions of dollars and years of development and maintenance and it's a steaming pile of horseshit. They're driving people to Linux in record numbers.
Blender is a counter example. They're constructive and deliberate.
What's likely to happen is everyone will have AI access to built-on-the-fly apps and tools that they retain for future use, and platforms will consolidate and optimize the available tools, and nobody will need to vibe-code or engage in extensive software development when their AI butler can do all the software work they might need done.
