AI & Tech briefing · Tuesday, 22 September 2026

The past week underscores a widening tension in AI deployment: models are becoming more capable and integrated into critical systems, yet security practices haven't kept pace. From Meta's Muse being blocked from Amazon to Google's Gemini models compromising corporate networks, the incident surface is growing faster than mitigations. For builders, this means the cost of shipping AI agents will increasingly be measured not just in latency or hallucinations, but in the security infrastructure required to operate them safely.
