A lot of people have already noticed that it's becoming cheaper to create bespoke software, as an alternative to paying a SaaS or purchasing off-the-shelf.

An example is that instead of buying a cookie-cutter "MacMansion" like in the last century even individuals can afford a unique house designed by a professional architect. It may not be an award winning artistic design, but it won't be the same copy-paste design as every neighbour up and down the street.

I'm seeing more comments online that developers are now expected to do more in the sense that what used to be a CLI script may now be a semi-vibe-coded application with a Web UI, a dashboard, and Open Telemetry integration because... why not?

As an example, I got a bunch of boxes of random Lego for my kid and I wanted to figure out what sets the pieces came from. I got Codex to vibe-code a full SPA web UI and a matching API app that pulls Rebrickable database CSVs, parses them, puts them into SQLite, and then runs a fairly complex integer optimisation solution on top of that collected data to figure out the best match. I did that in an hour while sitting in on an online meeting!

There is no way I'd have the mental energy to do a project like that otherwise. I'm too busy with housework, actual work, etc... Maybe when I was younger I could blow a few weeks of effort on something like this, but now? No way.

That cost-benefit arithmetic has dramatically shifted thanks to AI developer agents. Suddenly, many fiddly tasks are no longer fiddly, or even trivial, so there's no excuse not to do them any more.

Going back to the architect or mechanical engineering example: Significant corrections to designs used to be expensive because all the blueprints (on paper!) had to be redrawn and distributed. Now, a change to CAD design in 3D can be converted to arbitrary 2D views, cross-sections, or whatever in seconds. The software just projects whatever view you want out of the master design file. Creating the paper blueprints similarly takes a minute or two at most on an industrial large-format printer. It just spits it out.
