> AI systems will eventually be good enough (in 10-20 years) for companies to be able to deploy such systems with sufficient accuracy to afford the lawsuits.
I doubt that will be the case, because of the long tail problem. (same with self driving cars and other ML related problems).
In fact, we have counter-examples today. Newspapers (even reputable ones) can't get it right every time, despite the fact that they have both trained people and in theory they're setup to catch that w/ reporters - fact checkers - editors. And still, from time to time, they get it wrong. (and I'm not talking about purposefully getting it wrong, just honest mistakes.)
What will likely happen with a ruling like this is that the answers will be hedged and legalesed and muddied up the wazoo.
Newspapers have mechanisms like corrections and apologies that can be used to "right" a published falsehoods.
This relies on me being able to find out if a newspaper lies about me, which is usually easy since we can all go buy the same newspaper. With AI it is much harder to find out that it has been telling potential customers wrong things about my business.
You don't realize how this works do you? One incredible power (executive) governments have is to let people get away with crimes. People don't realize they have this power, but they control the public prosecutor who can legally choose to do something ... or not.
You will find references to this in stories where the government lets people get away with murder, because of course, that's dramatic for a story.
But when "bigger interests" (ie. the Chancellor's bank accounts) are at play, just to name one example, China gets to distribute lead-painted children's toys in Germany and doesn't have to accept liability. Russia gets to import sanctioned natural gas over illegally constructed pipelines. Etc.
As to how this goes within the EU, in the worst (but common) case, is as follows: the government chooses a company, and refuse to sue them. They have a tendency to choose the worst possible company, like using Palantir for policing Germans [1]. Then you find out most of the Chancellor's grandchildren are working there.
