There are so many situations where a little program can save one or a few people hours of work on tedious tasks, but wouldn't make sense to build or support given traditional software development overhead, but that becomes realistic with AI-assisted development. This is the idea of a sysadmin who has automated 80% of his job with a variety of shell scripts, borne out into many other roles.
We've seen the early phases of it with Replit and Lovable et al, but I think there's a big playing field for secure/constrained runtime environments for non-developers to be able to build things with AI. Low/no-code tooling increasingly seems anachronistic to me: I prefer code, just let an AI write and maintain it.
There's also a whole world of opportunity around the fact that many people who could benefit greatly from AI-built programs are simply not particularly suited to building them themselves, barring a dramatically more capable AI, where I think enterprising software engineers can likely spin out tons of useful stuff and address a client base they might never have previously been able to address.
