Could tiny magnets help a prosthetic limb follow its wearer?
Reviewed
Magnetic implants offer a new way to sense muscle movement. A three-person virtual control study is a useful step, with everyday prosthetic benefits still to be tested.

Understand how the pieces connect.
Models power tools. Connections supply knowledge and actions. Workflows organize the steps. Agents choose some of them. Governance keeps the whole process accountable.
Less jargon. More perspective.
A map of the landscape, with room for the questions that matter.
The AI landscape: a map, not a ladder.
Methods, capabilities, and systems overlap. Knowing the distinction makes the headlines easier to read.
An agent needs boundaries before it needs more tools.
What changes when AI can act, and how to introduce it without handing over the whole workflow.
The human in the loop needs a real job.
A review step only helps if the reviewer has the context, time, and authority to change the outcome.
A better answer
starts with a
better brief.
You bring the purpose and judgment. AI helps you explore the possibilities.
Build your own prompt“Explain [an idea I’m learning] in plain language. Give me a real example, show where the explanation breaks down, and ask three questions to check my understanding.”
Give the work a clear shape.
Explore an agent’s moving parts, build a repeatable workflow, and decide which information and actions belong inside its boundaries.
Inside an AI agent
The model is one part. The job, tools, state, checks, and stopping rules make it a working system.
Plugins, connectors, and skills
Separate packaged capabilities, reusable instructions, and the connections that let AI reach other software.
AI governance: who owns the outcome?
Turn good intentions into named responsibility, clear boundaries, evidence, and decisions throughout the life of a system.
Every industry. Different stakes.
Look at the work, the people, and the tradeoffs behind the technology.
IT & cybersecurity
Turn noisy signals into a clearer investigation.
Healthcare
Help people navigate information while protecting clinical judgment.
Education
Use AI to strengthen practice, not skip it.
Manufacturing
From process knowledge to carefully bounded assistance.
Finance & insurance
Make review easier without automating away accountability.
Creative work & design
Keep authorship, taste, and intent in the process.

What kind of future
do we want?
Explore AI beside us today, more connected possibilities ahead, and the choices that should stay ours.
Follow the threadStorytelling horizons. Not promises or predictions.
See the benefit.
Examine the cost.
AI can make work and information more accessible. It can also amplify mistakes, exclusion, and loss of control. Both deserve a clear-eyed look.
Explore benefits & harmsWhat it can help
Learning. Accessibility. Creative exploration. Less repetitive work.
What it can harm
Privacy. Trust. Opportunity. The freedom to choose.
Signals worth understanding.
Dated, sourced briefings. A place to make sense of developments—not chase every headline.
The FDA is asking a different question about generative AI.
A regulatory discussion is a signal about evaluation and oversight—not proof that every generative AI product is ready for healthcare.
Physical AI raises the stakes of getting it wrong.
