Stack Overflow快死了！新提问竟比内测时还少

TL;DR - Stack Overflow’s new-question volume has collapsed as developers shift toward private AI-assisted workflows, accelerating an earlier decline caused partly by hostile community dynamics. This threatens the supply of public, searchable, and correctable technical knowledge used by both people and future AI systems.

• Monthly questions fell from 207,000 at the 2014 peak to 1,304 in July 2026, with the sharpest decline following ChatGPT’s arrival.
• AI assistants eliminate much of the friction of public posting but turn reusable community knowledge into private, ephemeral conversations.
• High-reputation contributors are also leaving faster, potentially weakening expert participation and the creation of new expertise.
• Knowledge production may migrate to repositories, machine-readable documentation, and vendor interaction logs, but these are often less open than public forums.
