But the Amish are heavily excluded from society. Amish that refuse to use computers can't work most jobs. Amish that won't use credit cards can't buy things at cashless stores/restaurants. Amish that don't use electricity basically can't live in major cities.
But the Amish are nonetheless protected. Not by the law but by having a community of people around them willing to live with those same restrictions and provide for each other. I think that's much more likely to happen than legal protection also in the AI case.
Some places (including some places in the US) ban cashless stores. It seems reasonable to me to try to legally protect people who struggle to adapt to new technologies.
There are no legal carveouts for that.
