It's easy to migrate C/C++ to Rust if all you care about is the file extension (and have sufficient budget for tokens). Our team spent the past few months figuring out strategies, infrastructure, and tools to migrate to **idiomatic** Rust for actually improved codebases. 1/🧵

Agentic engineering, software factories, etc. are a fascinating topic. Obviously there are footguns, inflated expectations, and opportunities to slowly dig your codebase's grave everywhere – but think of #ai what you want, there's plenty of opportunity as well. 1/🧵

It's great to see how much we were able to achieve for the #emberjs ecosystem in the past ca. 2.5y. There's still – and there always will be – more work to be done but the ecosystem is now in a much better place than it was when we started.
