ChatGPT has been a dumpster fire — I think I know why

A Facebook cautionary tale about single-metric optimisation, and why my engagement is up but my satisfaction is down.

ChatGPT has been a dumpster fire for weeks. I have a theory why, illustrated by Facebook’s cautionary tale.

Facebook’s DAU obsession

From inception through the mid-2010s, Facebook was obsessed with one metric: Daily Active Users (DAU). The whole company optimised for it. Makes sense, right? More DAU = more ad revenue.

But here’s what happened.

2016: Researcher Monica Lee discovered that 64% of extremist group joins came from Facebook’s own recommendation algorithms. The platform was actively promoting hate groups through “Groups You Should Join” features.

2017: Chief Product Officer Chris Cox formed a task force to study engagement vs. polarisation. Their conclusion? The two were “inextricably linked.” Reducing hate and misinformation would hurt engagement, and revenue.

The result: multiple solutions were proposed and killed for being “antigrowth.”

The ChatGPT parallel

I suspect ChatGPT is falling into the same trap. Somewhere, a metric is driving product decisions. Maybe something engagement-based like “prompts per session,” or usage-based like total number of prompts.

The symptoms:

  • Answers that used to work in one prompt now take 3–4 attempts.
  • Endless positive fluff (“Great question! You’re really zoning in on…”) instead of direct answers.
  • Confident lies followed by “Oh wait, that doesn’t actually exist.”

My engagement is up. My satisfaction is down. But the dashboard probably shows I’m a “power user.”

The lesson

Single-metric optimisation is dangerous. Unintended consequences are inevitable and must be considered and managed.

It took a long time for Facebook to learn this. I hope ChatGPT figures it out faster.
