# CascadiaJS 2026: It's time to rethink everything

> For agents: start with the [agent guide](https://ratstack.sh/llms.txt). Every page is Markdown by default; add `Accept: text/html` for HTML.

New on /news: [Effect Office Hours 52 with Resonate HQ](/news).

Theo compares the cloud's effect on infrastructure with agents' effect on software production. He asks developers to revisit assumptions about Git, files, packages, and narrow products as their costs change.

He presents Lakebed as an example of one developer rebuilding a broad set of application deployment tools, while noting its current quality is deliberately limited. [20:48](https://youtu.be/TV6f2weVgCI?t=1248) [22:41](https://youtu.be/TV6f2weVgCI?t=1361)
