Introduction: Book Overview.

There is a moment before change becomes undeniable.

Not the moment when collapse occurs,

but the quieter one just before it,

when familiar structures still stand,

voices still reassure,

and the language of continuity remains intact,

even as its foundations have already shifted.

This book is written

in that moment. The Near Horizon Quandary does not predict the future.

It describes the present,

seen clearly, without the comfort of delay.

It is written for readers who sense that something essential in healthcare,

evidence, funding, and legitimacy has already changed,

even if the system has not yet found the words to admit

it. For decades, medicine,

markets, and public health were governed by distance.

Distance between intervention and outcome.

Distance between payment and proof.

Distance between approval and consequence.

In that distance, stories flourished.

Models substituted for memory.

Persuasion compensated for uncertainty.

Prevention thrived not because it failed,

but because it could not yet be fully seen.

That distance is collapsing!

Real-world evidence has turned time itself

into a witness.

Artificial intelligence has not invented truth.

Nor has it or will it be

something that reinvents it.

It is a tool that has revealed it.

The near horizon is not a metaphor.

It is the point at which visibility becomes irreversible.

This book is written in verse-like movements rather than arguments,

not to obscure meaning,

but to slow the reader just enough to feel the weight of

what is unfolding.

Each chapter examines a structure that once made sense

and asks a single,

uncomfortable question:

What happens to this structure

once reality

can no longer be postponed?

The answers are not offered as polemic or accusation.

They emerge as arithmetic,

as observation, as inevitability.

Nothing here is angry.

Nothing here is sensational.

That is what makes it unsettling.

You will not be asked to agree with every conclusion.

But you will be asked to look.

To sit with the idea that legitimacy may no longer be granted

in moments, but accumulated over time.

What replaces certainty is not despair,

but responsibility. What replaces persuasion

is stewardship.

What replaces approval

is alignment with reality.

The near horizon

does not threaten those who are willing to see.

It clarifies.

What follows does not argue this shift.

It watches it appear.
