Context
AI coverage on iByte separates shipped capability from roadmap talk. The practical lens is cost, access, safety, and what changes for builders and everyday users.
Why this matters
The immediate headline is only the entry point. The more useful question is who gains leverage, who faces new risk, and whether the change is durable or experimental.
What to watch next
Track whether the story affects total cost of ownership: subscriptions, compatibility, downtime risk, or support burden.
Practical takeaways
1) If money or security is involved, wait for primary sources. 2) Test changes on a small scale before committing. 3) Note what would falsify your current assumptions.
