Short answer: most of that side of ISAC is technically possible today, and the rest is plausible with near-term advances. The reason it isn’t real has far more to do with law, fragmentation, noise, and reliability than raw capability.

Below is a clean, system-by-system breakdown with no budget or legality constraints, just physics and engineering reality.

==== If you remove: ====
* Funding limits
* Legal/privacy restrictions
* Inter-agency silos

Then ~75–85% of ISAC’s “tapping into everything” capabilities are achievable today, with the remaining gap being accuracy, completeness, and confidence.

ISAC’s biggest exaggeration is how clean and decisive the intel appears, not whether it could be gathered.

==== ### ====
* Most modern cameras: - Are IP-based - Use common firmware - Are poorly secured
* Many already: - Stream to cloud services - Share metadata openly
* Computer vision can: - Track people - Re-identify across cameras - Detect weapons, posture, movement anomalies

With no legality constraints, ISAC could:
* Index nearly all cameras in a metro area
* Pull live feeds
* Stitch them into a city-scale view
* Auto-tag movement patterns

===== - Blind spots =====
* Low-quality feeds
* Weather, darkness, obstructions
* Deliberate camera sabotage

Verdict:
✅ Largely feasible today
❌ ISAC’s precision is overstated

==== ### ====

ISAC wouldn’t need passwords.

By monitoring:
* Probe requests
* Signal strength
* MAC addresses
* Access point metadata

It could:
* Track devices through cities
* Estimate crowd density
* Infer movement direction
* Identify repeat presence

Advanced systems already do this for:
* Retail analytics
* Airports
* Law enforcement

===== - MAC randomization reduces fidelity =====
* Devices turned off disappear
* Dense environments create noise

Verdict:
✅ Fully feasible, already deployed in parts of the real world

==== ### ====

Bluetooth is arguably the most realistic ISAC sensor.

BLE beacons leak:
* Device presence
* Device class
* Movement patterns

ISAC could:
* Track individuals through stores and streets
* Correlate device fingerprints
* Identify armed individuals by gear signatures
* Detect groups moving together

===== - Short range =====
* Requires dense receivers
* Can be spoofed or disabled

Verdict:
✅ Extremely feasible
⚠️ Localized, not omnipresent

==== ### ====

With unrestricted access:
* IMSI catchers
* Base station telemetry
* Call/data metadata
* Location triangulation

ISAC could:
* Track phones city-wide
* Identify burner devices
* Detect coordinated movement
* Flag sudden network blackouts

===== - Encrypted content still opaque =====
* Underground and dense urban areas degrade accuracy

Verdict:
✅ Feasible and already real in intelligence contexts

==== ### ====

ISAC wouldn’t need content—metadata is enough.

It could:
* Detect planning behavior
* Identify command nodes
* Correlate online activity with physical movement
* Flag sudden silence or spikes

This is exactly how modern intelligence works.

===== - Encryption hides content =====
* False correlations are common

Verdict:
✅ Completely feasible

==== ### ====

ISAC could tap into:
* Traffic lights
* License plate readers
* Smart meters
* Environmental sensors
* Building automation

This enables:
* Vehicle tracking
* Area control
* Movement prediction
* Infrastructure manipulation

===== - Vendor fragmentation =====
* Legacy systems
* Manual overrides

Verdict:
✅ Feasible, messy but powerful

==== ### ====

ISAC could correlate:
* Government records
* Commercial data brokers
* Retail transaction logs
* Biometric systems

This allows:
* Identity resolution
* Predictive profiling
* Behavior forecasting

===== - Data quality =====
* Stale or false records

Verdict:
✅ Already happening at scale

==== ### ====

Reality is:
* Noisy
* Contradictory
* Delayed

ISAC in the game filters this too well.

===== Real systems output: =====
* Probabilities
* Confidence intervals
* Ambiguity

ISAC speaks in absolutes for gameplay reasons.

===== No system can reliably tell: =====
* Who is hostile
* Who is desperate
* Who is bluffing

ISAC infers intent far better than reality allows.

==== - Detecting enemies with no electronics ====
* Identifying lone actors with discipline
* Operating in sensor-denied zones
* Preventing deliberate deception

Human adversaries adapt faster than systems.

==== If you strip away funding and legality: ====
* ISAC’s data-collection and sensor-fusion abilities are mostly real
* Its reliability and decisiveness are fictionalized
* Its authority and integration are the real stretch

The uncomfortable truth:

: 

The least realistic part is that people would ever agree to let one system see and decide so much.

If you want, next we can:
* Walk through how ISAC would track you in a city today
* Analyze how rogues would evade ISAC sensors
* Break down which ISAC feeds are the most valuable tactically
* Or compare ISAC’s surveillance to real intelligence fusion centers
