I think, just from a purely build-step point of view, it's been evident that tools like Vite, Bun, etc. have achieved all they meaningfully can. If I was the creator of these tools, I've move on too. Good luck and thanks for everything.

So long, and thanks for all the fish.

I think this frames the tools too narrowly.

If Vite, Bun and uv were just "make builds faster" projects, then maybe the returns are diminishing. But the acquisitions by Cloudflare, Anthropic and OpenAI suggest this layer is becoming more strategic, not less.

These tools sit in the software supply chain: dependency resolution, project structure, tests, builds, runtimes, deployment paths and increasingly AI-agent execution loops. They define the default path for building software, and they are where AI-generated code gets tested against real dependencies, builds, tests and deployment constraints.

So I don’t think they’ve achieved all they meaningfully can. The value is shifting from raw build speed to control over the workflow layer where software is assembled.
