We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.
The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

Ben Franklin on inoculation, after his son died from smallpox.
“In 1736, I lost one of my sons, a fine boy of four years old, by the small-pox, taken in the common way. I long regretted bitterly, and still regret that I had not given it to him by inoculation”.

1. LLM-generated code tries to run code from online software packages. Which is normal but
2. The packages don’t exist. Which would normally cause an error but
3. Nefarious people have made malware under the package names that LLMs make up most often. So
4. Now the LLM code points to malware.

LLMs hallucinating nonexistent software packages with plausible names leads to a new malware vulnerability: "slopsquatting."
LLMs can't stop making up software dependencies and sabotaging everything

Been there done that!
how to boost productivity:
- be unaware that a feature exists;
- file a ticket for it and put in on the planning doc;
- discover the feature months later working exactly as you described, remove from the roadmap;
- boom 2 weeks of engineering time saved

If you have the strength within you, read the entire thing before responding and don't repost anything but this first post. Context collapse is the issue.

As a blanket notice, turning off replies when posts escape containment usually happens not because I don't want to encourage discussion, but because I'd rather people look at and think about the words I wrote than go spelunking for arguments.
