Bier's AI-spam apocalypse prediction: 90 days later, channels still work
X's Head of Product forecast AI-driven spam would render email and messaging unusable within 90 days. The deadline has passed; communication channels remain functional despite rising automated noise.
Three months ago, Nikita Bier — Head of Product at X — posted a stark prediction: within 90 days, iMessage, phone calls, and Gmail would be "so flooded [with spam & automation] that they will no longer be usable in any functional sense." The 90-day mark passed this week. Communication channels are still working.
Bier's forecast framed the threat as AI-driven: cheap language models and voice synthesis tools enabling spam at unprecedented scale. The prediction drew attention in AI circles because it named a specific timeline and specific platforms, not just a vague "someday" warning.
What stands out
- 01Spam volumes have risen, but filters are holding. Gmail users report more AI-generated phishing attempts in recent months, but Google's spam classifier still catches the majority. Some users note an uptick in borderline messages landing in primary inboxes, but the platform remains usable for most accounts.
- 02Phone spam is worse, but not catastrophic. Robocall volumes climbed in early 2026, and voice-cloning scams are more common. Carrier-level call screening (AT&T Call Protect, T-Mobile Scam Shield, Google Phone's AI screening) has improved in parallel. The arms race is real, but "unusable" overstates the current state.
- 03iMessage and WhatsApp see less pressure. End-to-end encrypted platforms with contact-based filtering have proven more resistant to mass automation. Spam on iMessage remains rare for users with default settings enabled.
- 04The 90-day window was too tight. Even if AI-driven spam scales exponentially, platform defenses and user behavior adapt over quarters, not weeks. Bier's timeline assumed attackers would outpace defenders faster than the data supports.
