It annoys me greatly, that I have no tick box on Google to tell them "go and adapt models I use on my Gmail, Photos, Maps etc." I don't want Google to ever be mistaken where I live - I have told them 100 times already.
This idea that "no one wants to share their data" is just assumed, and permeates everything. Like soft-ball interviews that a popular science communicator did with DeepMind folks working in medicine: every question was prefixed by litany of caveats that were all about 1) assumed aversion of people to sharing their data 2) horrors and disasters that are to befall us should we share the data. I have not suffered any horrors. I'm not aware of any major disasters. I'm aware of major advances in medicine in my lifetime. Ultimately the process does involve controlled data collection and experimentation. Looks a good deal to me tbh. I go out of my way to tick all the NHS boxes too, to "use my data as you see fit". It's an uphill struggle. The defaults are always "deny everything". Tick boxes never go away, there is no master checkbox "use any and all of my data and never ask me again" to tick.
