„There will still be joy in programming. Just as there’s joy in joinery, knitting, and hiking.“

you could not have literally not picked worse examples though…

The cost of turning written business logic into code has dropped to zero. At best, near-zero.

The cost of integrating services and libraries, the plumbing of the code world, has dropped to zero. At best, near-zero.

What does that mean for the future?

Can't wait for the loosened up, non-perfect, but quickly shipped AI-enhanced updates to hit my banking and insurance services next year.

Im sure there will be no issues there at all.
software development in 2026 is going to require some to loosen up a little code doesn't have to be as perfectly crafted the way we did it pre-ai call it slop if you want, but if you're still demanding perfection on every pr while your competitors are shipping "slop" that works.. you're fighting from a disadvantaged position shipping velocity matters more than perfection

GitHub Actions charging per build minute for *self-hosted-runners*? Shit's about to hit the fan lol
You are receiving this email because your usage of GitHub Actions may be impacted by upcoming changes to GitHub Actions pricing. What’s changing, when On January 1, 2026, all customers will receive up to a 39% reduction in the net price of GitHub-hosted runners, depending on the machine type used. On March 1, 2026, we are introducing a new $0.002 per-minute GitHub Actions cloud platform charge that will apply to self-hosted runner usage. Any usage subject to this charge will count toward the minutes included in your plan. No action is required on your part.
