Our new health insurance premium feels more like a shakedown‼️
Thank you, @politicsgirl.bsky.social , for sharing your story. You’re right—there are millions like you.
Our new premium is over $3K/month for a family of three. Could we scrape it together? Maybe. Should we have to? No.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.
