A human’s guide to keeping up with the singularity.

3 developments worth understanding.

Meta puts an agent inside a conversation.

Meta says Muse can send email or book travel using its own cloud computer, asking for approval before emails or purchases. You can use Muse or WhatsApp to assign a task, then leave it running.

Access & limits. Meta says US access is rolling out on iOS, Android and the web. Reliability has not been tested by AI-Buzz.

Why it matters · AI-Buzz’s readingMessaging could become a way to delegate computer work. The useful test is whether the agent completes a task with less supervision than doing it yourself.

Meta’s Muse announcement
Permissions, cost and what comes later
Your control
Meta says Muse asks before sending email or making purchases. You choose which services it can access and can disconnect them.
Cost
The announcement describes free use and subscription plans, without giving prices or usage limits.
Later
AI-glasses access and the Confidential VM are future plans. Neither is part of the announced US rollout.

Google adds conversation to Gmail, Docs and Keep.

Google announced voice features for finding email, drafting documents and turning spoken thoughts into notes. They work inside familiar apps, with different subscription requirements.

Access & limits. The article says Gmail and Keep are rolling out to Google AI Plus, Pro and Ultra; Docs to Pro and Ultra. Workspace business access is “coming soon.”

Why it matters · AI-Buzz’s readingThe interesting shift is from dictating words to asking an app to organize or find something. A launch headline still needs an answer to “Does my account get it?”

Who gets access—and what the earlier announcement said
Permission
Google says Docs Live can draw on Gmail, Drive, Chat and the web with your permission.
Source discrepancy
Google’s AI-generated summary suggests business rollout is happening now. Its bylined article says “coming soon.” Business availability is not established; we have not tested an account.

Two announcements, different access

Google’s May post names Pro and Ultra subscribers, with a business preview planned for summer. September names Plus for Gmail and Keep, while business access is still described as coming soon.

These are two dated announcements read now. They do not establish whether the business preview happened or when an account received access. Earlier page revisions are unavailable, so this is not a verified history of availability.

Runway shows generated worlds you can steer.

GWM Worlds 2 generates video and sound in response to character, scene and camera controls. Runway’s demos show a scene continuing as the player changes what happens.

Access & limits. Research preview. The announcement offers a contact form; it does not establish public access.

Why it matters · AI-Buzz’s readingGenerated video could become something you interact with. A convincing scene still leaves the harder question of whether a whole game can stay coherent.

Runway’s research and demos
What the demos show—and their limits
Output
Runway reports continuous 720p video at 24 frames per second with generated audio. These are vendor-reported capabilities.
Limits
Runway says examples with actions written in advance produce better quality than its live demo, which maps keys and mouse input to premade prompts. Fast camera turns can degrade visuals, and the model’s memory is imperfect.
