Over the past one and a half years, Stack Overflow has lost around 50% of its traffic. This decline is similarly reflected in site usage, with approximately a 50% decrease in the number of questions and answers, as well as the number of votes these posts receive.
The charts below show the usage represented by a moving average of 49 days.
What happened?
Ironic, since one of ChatGPT’s biggest weaknesses is that it’s an archive of the old ways of doing things. You can’t filter by time on ChatGPT, and ChatGPT isn’t being retrained on the latest knowledge live. These aren’t inherent to GPT, so it’s possible that a future iteration will overcome these issues.
On ChatGPT, if a solution doesn’t work, you can ask in real time for a different one. On SO, your post just gets locked for being a duplicate.
Asking in real-time wouldn’t help in this scenario (e.g. some mirror is no longer accessible). If anything, it’d just lead you further astray and waste more time, because GPT’s knowledgebase doesn’t have this knowledge.
