◆ FROM THE DESK
Welcome back. There's a theme running through this week's reading, and we didn't plan it: everybody wants AI on the plant floor, and very few plants have the data foundation to feed it. A panel at the Industrial AI Summit put a name to the missing layer. Palo Alto's new report put numbers on how little of our own OT estate we can even see. And on the show, the man who co-invented MQTT gave the cleanest three-word answer we've heard all year — decouple, single source of truth, then AI.

DATA & AI · INDUSTRIAL AI SUMMIT
The layer nobody built: why factory data never reaches AI
Ten to twenty years of sensors and connectivity, and the data still doesn’t land anywhere an AI model can use it. At the Industrial AI Summit 2026, Jonathan Alexander (Albemarle), Peter Sorowka (Cybus) and Kudzai Manditereza (HiveMQ) mapped where it gets stuck. Collection is solved. Historisation is widespread. Contextualisation is simply missing — the equipment relationships and operating conditions that make a reading mean something still live in the heads of your operators, not inside any system. Their second point lands just as hard: point-to-point, application-centric integration is why so many plants never get past the pilot. Every new use case pays for its own plumbing.

OT SECURITY · NEW RESEARCH
68% can’t see their own OT assets in real time
Palo Alto Networks’ 2026 State of Critical Infrastructure Cybersecurity report surveyed more than 1,600 security leaders across 11 countries and five sectors, and it is uncomfortable reading. 60% had a significant breach in the past year — half of those reporting physical safety concerns as a result. 68% lack complete, real-time visibility of everything connected to their OT networks, and 42% name legacy, unpatchable OT assets as their single biggest risk. Then the timing gap: 29% of 2026 CVEs were exploited inside 24 hours, against an industry average of 55 days to deploy a patch. Tool sprawl is part of the problem — seven disparate security systems on average — and 74% still have not integrated IT and OT security operations.

ROBOTICS · PHYSICAL AI
A 99% robot is not a 99% automated job
A useful antidote to humanoid demo season, from Nicolas Sauvage of TDK Ventures. Take a workflow of 100 sequential physical actions. At 99% success per action, the odds of getting through all 100 first time are 36.6%. At 99.9% it is 90.5%; at 99.99% it reaches 99.0%. Small reliability gaps compound brutally across a real job, which is why a robot that looks flawless on stage can still be nowhere near ready to work unattended. His argument: dexterity is a closed-loop system — vision, position, contact, force, grasp, movement, recovery — not a hand with more fingers. The customer does not buy degrees of freedom. They buy useful work.

Ep. 60 — Arlen Nipper: From Pipeline SCADA to 15 Million Tags
It is out. Arlen Nipper — co-inventor of MQTT, President and CTO of Cirrus Link Solutions — joins Phil to trace the line from a 1999 Amoco pipeline on a satellite link that charged by the byte, to today’s 15-million-tag deployments running to a contractual three-second SLA. MQTT, Sparkplug, the Unified Namespace, what is coming in Sparkplug v4, and a blunt order of operations for anyone being asked to bolt AI onto OT data.

CIRRUS LINK SOLUTIONS
Twenty-five years of MQTT: inside Cirrus Link
Our EP60 guest Arlen Nipper co-invented MQTT in 1999 with Andy Stanford-Clark, to pull an Amoco oil pipeline back over a satellite link that charged by the byte. Twenty-five years on, he is President and CTO of Cirrus Link Solutions — the company behind the Sparkplug specification and the Ignition MQTT modules that a very large share of this audience already runs in production.
What that lineage looks like today, in Arlen’s own numbers from the episode:
|
• 15 million live tags at a contractual 3-second SLA. One active deployment moves 15 million tags continuously, many changing every second, with a guaranteed 3 seconds from field change to the Ignition platform. The mechanism is report-by-exception — “that’s really the only way you’re going to get the bandwidth that you require.”
|
|
• 524 sites, one control room. NextEra Energy consolidated 524 solar, BESS and wind sites into a single Remote Operations Centre: site to OT broker to Ignition to IT broker to cloud.
|
|
• A Unified Namespace market that went from zero adoption to more than US$2 billion.
|
|
• Sparkplug v4 is coming, and it takes on alarm propagation and event pipelines.
|
His framework for anyone being asked to bolt AI onto OT data is three words in order: decouple, establish a single source of truth, and only then apply AI.
|
“I haven’t had one data centre customer yet that didn’t come to us and say, ‘okay, we’re gonna use MQTT.’”
— Arlen Nipper, President & CTO, Cirrus Link Solutions. Co-inventor of MQTT, key author of the Sparkplug specification, 47+ years in SCADA, and the inaugural Lifetime ProveIt! Award recipient (2025).

SmithTek approved under the On-Farm Connectivity Program
Following last issue’s Solaris launch, more good news out of WA: SmithTek is now an approved supplier under the Australian Government’s On-Farm Connectivity Program, meaning eligible producers can claim a rebate of up to 50% on qualifying telemetry hardware and software. If remote water, irrigation or off-grid monitoring is on your list this season, that is a meaningful change to the numbers.
