Dynamic Software

Software has always been deterministic. You write instructions, the machine follows them, you get a result. The same inputs produce the same outputs. That's been true since the first punch card.

2024 changed this. Not incrementally — categorically. When language models became capable enough to make real decisions, the control flow of software stopped being a fixed graph and became a living thing.

I call this Dynamic Software. Not "AI-powered" (everything is AI-powered now). Not "intelligent" (that's too vague). Dynamic — because the execution path isn't determined at write-time, it's determined at run-time, by reasoning.

Think about what this means practically. In static software, a bug is a miswritten instruction. In dynamic software, a bug might be a misaligned objective. The failure mode changes. So does the debugging methodology. So does the testing strategy.

We're still in the early innings of understanding what it means to build Dynamic Software reliably. The frameworks are immature. The mental models are borrowed from old paradigms. The best practices are being written right now, by teams shipping real products.

What I know for certain: the engineers who internalize this shift earliest will have a compounding advantage over those who treat AI as a feature to bolt on. Dynamic Software isn't a feature. It's a new medium.
