You can just build things
May 06, 2026

We now live in a world where you can just build things! I once heard of software development described as “building castles in the clouds” because it is generally abstracted away from physical reality, and that has never been more true than now. Castles abound in my sky!

Jevons Paradox states that “technological improvements which increase the efficiency of a resource often lead to an increase in its total consumption, rather than a decrease”. Because coding is so much cheaper now, the activation energy for whether I should build a tool to scratch a particular itch is so low that I will kick a project off on a lark. I don’t finish all of them (one of the reasons activation energy was previously higher), but I finish enough that I feel my agency is through the roof. Castles not only abound in various states, but the decision to embark on a new one is effortless. For me, the paradox holds - I spend more total hours coding now (or doing something akin to coding) than I did when each project cost more.

I’ve long said that agentic coding is great for people who like to build things but bad for people who like to craft things. If you get enjoyment out of writing a function just so, or a frisson from a class that elegantly allows an extension you hadn’t even thought of, then agentic coding tools will leave you feeling empty. If, on the other hand, you just want something to exist, then this newfound ability is the ultimate freedom. I expect most people exist in a confusing jumble of multiple points on this spectrum. In some ways, I know that I like craft - woodworking, in another context, where a factory-built piece of furniture would have been cheaper and faster to an end result. That makes it a little mystifying why for now, with code, I’m still marvelling at how much I can build. Perhaps I’ll lose my delight in manifesting personal pieces of software, but for now - just build things!

Here is a curated list of cloud castles I’ve built over the last year:
