OpenAI’s release of GPT-5 backfired: instead of excitement, users felt betrayed by a forced upgrade that stripped away the warmth and reliability they had come to rely on in GPT-4o.

Big picture: There's a larger, unsettling truth: people are forming real bonds with digital assistants they don’t control, and when companies change them, the emotional fallout is very human.
