mattbrowndev, (I work at Slack, opinions my own) A bunch of people are sharing viral social media posts saying that we train LLMs on customer data. It's a story that slots neatly into the hype/doom narrative around AI.
But it's not true — we even wrote a whole blog post about it last month: https://slack.engineering/how-we-built-slack-ai-to-be-secure-and-private/
Not discounting the other concerns around LLMs (e.g. hallucinations, environmental impact) that are totally legitimate.
