We always could. That has been true since the days we programmed computers by plugging jumper wires into a panel.

Formal verification is a nice idea but it's a big hill to climb from where we're at. Most people can't even get agents to robustly E2E QA code, which is a much smaller hill to climb for (probably) larger benefits. I'm sure this area will improve over time though, since it is an eventual unlock for fully autonomous engineering.

"Imagine market infrastructure where agents must prove, before executing, that their actions satisfy regulatory constraints, risk limits, fairness properties, and eventually machine-checkable proofs of Pareto efficiency of market mechanisms. This is a big, hairy, ambitious goal. Not “we reviewed the code” but “the system verified the proof.” The agent that cannot demonstrate compliance cannot act."

But you don't really need complete formal verification to get these benefits. TDD gets you a lot of them as well. Perhaps your verification is less certain, but it's much easier to get high automated test coverage than it is to get a formally verifiable codebase.
I think AI assisted coding is going to cause a resurgence of interest in XP (https://en.wikipedia.org/wiki/Extreme_programming) since AI is a great fit for two big parts of XP. AI makes it easy to write well-tested code. The "pairing" method of writing code is also a great model for interacting with an AI assistant (much better than the vibe-coding model).

The fact that we're reading about it here today and have read about it in the past weeks is one piece of evidence. Another is that we hadn't been reading about it in the past months before November. Opus 4.5 and GPT 5.2 have crossed an usefulness frontier.
Anecdotally, I've been having some success (guiding LLMs) writing Alloy models in the past month and ensuring conformance with code. Making these would've been unjustifiable from ROI perspective fairy tales just this summer. The landscape has changed qualitatively.

This has always been the case?
