> It's not profitable to use AI for wholesome and healthy things for people, so nobody does
The purpose of the ML systems I build is to detect when things go wrong in order to keep people safe. These systems are both important and extremely valuable. They just aren't quite as sexy as the latest computer vision or large language models. But that's ok. Normal people only become aware of such systems when things go horribly wrong. It's sort of like plumbing in that regard.
Even if ads were the biggest use of AI today, a glass-half-full view would be that other markets will benefit from the AI development done today for ads, as the performance gets sufficiently good enough for those fields too.
Blaming it on politics leaves you with no actions to take beyond trying to talk people into acting against their incentives - which you can do, but it's not easy to get people to change their minds en-masse.
Yes, which is why it's important to be politically involved, governments are the ones with power to change incentive structures at the scale of large companies or society-wide. I do agree with your first paragraph, but your second paragraph does not make sense to me, it's not "blaming it on politics", politics is the exact mechanism to enact the changes you refer to in your first paragraph.
That's not AI, that's capitalism. It's not profitable to use AI for wholesome and healthy things for people, so nobody does. It's more profitable to cram advertisements into every corner of our life, it's more profitable to mine our personal information and personal friend networks, it's more profitable to sell us a service instead of a tool. The next time you're upset at how technology is being used, think about who benefits and what their politics are, because everything is political.
