Wildly understating this part.
Even the best local models (ones you run on beefy 128GB+ RAM machines) get nowhere close to the sheer intelligence of Claude/Gemini/Codex. At worst these models will move you backwards and just increase the amount of work Claude has to do when your limits reset.
These kinds of risks can only be _consented to_ by technical people who correctly understand them, let alone borne by them, but if this shipped there would be thousands of Facebook videos explaining to the elderly how to disable the safety features and open themselves up to identity theft.
The article also confuses me because Apple _are_ shipping this, it’s pretty much exactly the demo they gave at WWDC24, it’s just delayed while they iron this out (if that is at all possible). By all accounts it might ship as early as next week in the iOS 26.4 beta.
