It does strike me as a little odd that they didn't hire a developer earlier and got the code written. Sitting back and waiting for someone to drop by and present a solution is a little naive, but it's also the world we built in the IT industry over the past 20 years. When I started my first job, we frequently had customers ask for bespoke solution, most of which was small one week to a few months of work. Multiple co-workers in the mid 2000s has side businesses, where they did contract development, most of which was these types of small one off solutions. Most of the software companies, in my area, that did these types of jobs are all gone now.
If AI accidentally created an environment where people can once again solve small programming problems on their own and massively improve the workflows I'm all for it. Serves the industry right for abandoning these customers.
