# Problems: what people in data, tech and AI struggle with

> Problems tracks the problems people state in public posts about data, tech and AI (Hacker News, Reddit, Stack Overflow, GitHub issues, community forums, Bluesky, Mastodon, YouTube, App Store reviews and other fru.dev sites), grouped into short plain problem statements with daily counts, momentum, the companies involved and a link to every post. It grows every day. By fru.dev.

So far: 332 problems (201 corroborated by 3 or more posts from 2 or more people or places) from 1,735 problem posts, 498 of them in the last 7 days, 146 companies and products, 177 sources read. A scan runs daily at 05:25 UTC with a lighter pass at 17:25 UTC. History is append-only (/changes). Last rebuilt: 2026-09-25 18:17:59 UTC.

## About this data

Problems from public posts only: Hacker News, Reddit, Stack Overflow, GitHub issues, community forums, Bluesky, Mastodon, YouTube, App Store reviews and other fru.dev sites. A scan reads them every day at 05:25 UTC with a lighter pass at 17:25 UTC, and rules (not people) group posts that state the same pain; clusters backed by fewer than 3 posts from 2 people or places are marked unverified. Excerpts are short, attributed and link to the originals. The list grows as new problems appear. Not advice. Logos via logo.dev; trademarks belong to their owners. Anonymous usage stats via Google Analytics.
