I can safely say this article is bullshit. While there are a lot of programs ongoing to allow builders to adopt GenAI tooling, and while there is definitely a lot of communication ongoing around those programs, nobody is, at all, forced to use any of the AI tools. None are installed by default or enabled by default anywhere, and everyone is free to completely ignore them.
That said, is there an increase in expectations? Yes. But that's just normal Amazon in an employer's market, and has nothing to do with LLMs and GenAI.
The comparison to Microsoft where we can witness in public the .Net maintainers fighting with the shit code generated by Copilot on their repos is ridiculous. Amazon is probably one of the companies pushing the least and being the most prudent about GenAI adoption.
