‘Cambridge Analytica’ feels like a meaningless buzzword at this point. But the main thing I’d say here is that, at least in most companies, the things you write in emails or on the corporate wiki or whatever are not private to you – they are owned by the company. That doesn’t mean people don’t sometimes use corporate email for various private things, and it will certainly be used for sensitive things, eg it would be bad if something had read all the emails and could then answer questions like ‘is the firm thinking of firing X?’. But fundamentally, I think AI applied to corporate information retrieval is pretty different to whatever is meant by ‘next generation of Cambridge Analytica’.
