At 2 a.m. in the emergency room, seconds decide outcomes.
Soon, those same decisions will be shaped by AI models, planetary-scale data, and infrastructure that lives beyond Earth.

I’m Dr. Harvey Castro, an ER physician and Chief AI Officer at Phantom Space, working at the intersection of medicine, artificial intelligence, and space-based computing to help healthcare move from reactive to predictive without losing its humanity.

For over 20 years, I treated crisis after it walked through the door.
That experience shaped my conviction: the future of healthcare isn’t faster reactions, it’s earlier signals.

Today, I focus on how:

AI + clinical data

Edge computing, satellites, and orbital data centers

Human-centered design

can work together to anticipate illness, reduce burnout, and protect patient safety at scale.

What I’m working on now

Serving as Chief AI Officer at Phantom Space, helping design AI strategies that leverage space-based data pipelines and resilient orbital infrastructure for real-world health impact

Advising health systems, governments, and regulators on safe, ethical, deployable AI

Translating frontier technologies generative AI, ambient sensing, edge inference into tools clinicians can actually trust and use

Chief Executive Officer

Medical Intelligence Ops, where we are pioneering the integration of Large Language Models (LLMs) into healthcare. Our physician-led team is committed to transforming patient care and hospital operations through intelligent solutions.

We are automating decisions we haven’t fully defined.

That’s the risk hiding in plain sight.

Before automation, humans absorbed ambiguity.
Context.
Judgment.
Nuance.

AI doesn’t absorb gaps.
It locks them in.

If a decision isn’t clearly defined,
AI will still execute it.
At scale.
With confidence.

Healthcare learned this the hard way.

When criteria are vague, automation doesn’t clarify them.
It hardens them.

Memorable line:
If you can’t explain a decision, you shouldn’t automate it.

AI doesn’t remove ambiguity.
It forces it to choose.

The leadership question is simple and uncomfortable.
Do we actually agree on how this decision should be made?

If the answer is no,
automation will decide for you.

Best practices before automating decisions:

Define decision boundaries in plain language
Document assumptions and failure modes
Separate judgment from execution
Require human review where stakes are high
Refuse to automate what cannot be explained

AI doesn’t just execute decisions.
It exposes the ones we never fully understood.

Organizations that recognize this early will avoid scaling the wrong logic.

AI isn’t coming to healthcare.

It’s already here and most leaders aren’t ready.

This morning, I had the honor of serving as the keynote speaker at the 2026 Executive Leadership Conference for the American Academy of Physician Associates.

In the room: 300+ #PA and #NP leaders from across the country.

Not beginners.

Decision-makers.

The people who determine whether AI becomes noise…
or becomes patient impact.

We didn’t talk about shiny demos.

We talked about consequences.

Here’s what we unpacked:

• The 10M global workforce shortage and why AI + Clinician is no longer optional

• Automation bias and the “GPS effect” quietly reshaping clinical judgment

• How AI hallucinations could create Medicare fraud exposure

• Dataset bias in dermatology and genomic blind spots

• The rise of shadow AI inside hospitals

• And why empathy remains the most advanced technology in medicine

But the most important conversation wasn’t technical.

It was responsibility.

AI moves exponentially.
Healthcare systems move linearly.

That gap creates pressure.

Pressure creates mistakes.

And mistakes in medicine cost lives.

For years, I’ve said:

AI + Clinician > AI alone or Clinician alone

Today, I updated it:

AI + Clinician = Survival
Not because AI replaces us.

But because the demand curve, burnout rates, and complexity of care are outpacing human capacity alone.

AI is not the captain of the ship.

You are.

AI is the lighthouse.

Grateful for the thoughtful questions on governance, regulation, and responsible implementation and for the leaders who stayed after to wrestle with the hard parts.

The future of healthcare won’t be written by algorithms.

It will be written by clinicians courageous enough to shape how those algorithms are used.

The real question is:

Will we design AI around medicine…

Or redesign medicine around AI?

Everyone talks about AI making cities smarter.

Fewer people talk about what happens when those systems fail.

As AI becomes embedded across transport, energy, healthcare, and public services, something new emerges:

Interconnected intelligence.

But interconnected systems have a hidden property.

When one breaks…
others can fall with it.

This is one of the central questions we explored in this new whitepaper on AI governance for digital public services and smart cities.

Proud to contribute alongside an incredible group of global experts.

One insight stood out:

Smart city systems are becoming critical infrastructure.
And critical infrastructure must be designed for resilience not just efficiency.  

That means thinking about:

• interoperability across vendors
• transparency and explainability
• fallback modes when systems fail
• human oversight in high-risk decisions

From my perspective working on AI infrastructure at Phantom Space, resilience may also require rethinking where compute lives.

Edge.
Cloud.
And eventually space-based infrastructure designed to keep AI systems operating even when terrestrial systems fail.

Because the future of AI isn’t just smarter software.

It’s resilient intelligence infrastructure.

Curious what others think:

What is the biggest risk we face as cities become AI-driven?
