In my opinion, data and documents are the real AI benefit, or threat, to developer jobs.

Specifically, how good a company's data is will determine how effectively it can leverage AI in the future. The public data is pretty much mined to exhaustion, and the next big data source will be in-house documentation, code repos, data lakes, etc. If you work for a company where that's been built, maintained, and organised then the effectiveness of AI is going to be mind-blowing. Companies that have maintained good docs be able to build new things, maintain old things, and migrate things to cheaper modern stacks easily. That will lead to being able to move fast and deploy new AI-driven services easily and cheaply. Revenue will follow.

Conversely, at companies where documentation and code organisation have been historically poor, AI will struggle. Leaders will see it as a benefit, and be baffled at why their company can't realise the value of it. They'll quickly blame developers for not being able to use it, and that'll lead to people's growth stagnating or possibly layoffs. Eventually competitors will eat the company's lunch because they'll just be able to move on opportunities much faster.

I've resolved that in any future job hunt I'm going to make asking about docs, data, and repos a priority...
