That researcher I met at a coffee shop changed how I see AI training data

I was grabbing a latte in Portland last Tuesday and this woman sat down next to me with a laptop full of spreadsheets. She noticed I was reading an article about large language models and asked if I worked in the field. Turns out she spends her days labeling ambiguous medical images for a hospital AI. She told me about one x-ray where three different doctors gave three different answers on what they saw. She said she has to pick one answer to feed into the model, even when she knows it's probably wrong. That stuck with me because we talk about AI training like it's all clean data, but real human input is messy. Has anyone else run into the people behind the scenes who actually label this stuff?

aint that deep. one person labeling x-rays isnt some big moral crisis. thats just how training data works someone has to do it. ive seen way worse data in my day like mislabeled pics or bots doing the work. one bad call on a blurry image probably wont crash the whole system.

Are you saying that as long as the model mostly works, the occasional mistake by a tired person labeling data is just how it goes?
