From Prototype to Production: The 70% Wall

From Prototype to Production: The 70% Wall

There is **no measurement** behind the famous "70%" — the author himself writes that he took it from a tweet. What has been measured: **37%** of companies can show any bottom-line effect at all from AI, and that share has **not moved** in a year — while 80% feel personally more productive. That is the wall.

Buy or Build with AI? The New Calculation

Buy or Build with AI? The New Calculation

In a survey of 1,719 respondents, **32%** of companies decided **not to buy** at least one piece of software because they built it in-house with AI tools. In the same survey, though, the bottom-line impact attributed to AI **sits at 37% — exactly where it was a year ago.** Building got cheaper. The return did not get better.

Scheduled and Background Agents

Scheduled and Background Agents

One vendor's documentation describes its own interface like this: **"a green status means the session started and exited without an infrastructure error. It does not mean the task succeeded."** That one sentence sums up the entire problem with background agents. And according to one measurement, **more than a third** of failures are exactly this: the agent **does not know when to stop**.

Browser and Computer-Use Agents: Real Uses

Browser and Computer-Use Agents: Real Uses

In April 2024 the best model solved **12.24%** of computer-use tasks; a human solved **72.36%**. In August 2026 the best number is **85.96%**. So the capability is there — the question is the cost. And it does not grow linearly, it grows **with the square of the step count**: 6.7 times more steps means a **34 times bigger bill**. The biggest turnaround, though, is somewhere else entirely: the agent that **writes code instead of clicking** is cheaper and more accurate at the same time.

Permissions: The Least-Privilege Agent

Permissions: The Least-Privilege Agent

Three things are needed for a data leak: **private data**, **untrusted content** and **an outbound channel**. Any two of them on their own are safe — all three together are not. And this is not theory: according to a study of 7,973 live servers, **40.55% of them expose their tools with no authentication**.

Human in the Loop: Where to Put the Approval

Human in the Loop: Where to Put the Approval

The human who approves is not a neutral safety layer. In a 2026 randomised clinical trial, **44 doctors, after twenty hours of AI literacy training**, still performed **14 percentage points worse** whenever the AI handed them a wrong recommendation. Training does not protect against this. What does: **few approval points, but real ones.**

Agent Reliability Math: Why Twenty Steps Fail

Agent Reliability Math: Why Twenty Steps Fail

0.98 to the twentieth power = **66.8%**. That one multiplication explains the feeling that an agent is "almost right, but it always breaks something somewhere". And the reverse is harsher still: **at twenty steps, a 90% end-to-end success rate demands 99.475% per-step accuracy.** Not 90%. This whole topic lives in the gap between those two numbers.

No-Code Automation with AI: Which Platform?

No-Code Automation with AI: Which Platform?

Price is not what decides, **the billing unit is**. Five large platforms, five different units — and the same daily automation with twenty steps consumes **900** units on one and **18,000** on another. That is a twentyfold difference for exactly the same work. Plus one correction that many comparisons get wrong: **n8n is not open source.**

Your First Automation That Is Actually Useful

Your First Automation That Is Actually Useful

Most companies start where the return is worst. According to a report covering 52 organisations and 153 executives, roughly **70% of the AI budget goes to sales and marketing**, while **back-office processes** delivered faster payback and cleaner cost reduction. And there is one number that rearranges everything: for an automation running once a day, **the platform fee is typically more than a hundred times the model cost.**

Built-In Office AI: Is the License Worth It?

Built-In Office AI: Is the License Worth It?

The license fee is not the bottleneck. Even the measurement with a control group lands on **4.7 hours a month** saved, while break-even needs **under an hour and a half** at most pay levels. The real risk sits elsewhere: that colleagues never use it, and that checking the output eats the gain back. Plus in 2026 the limit moved out of the price and into the **quota**.

Customer Support Replies with AI

In a peer-reviewed study of 5,172 agents, an AI assistant raised the number of issues resolved per hour by **15%** — over 30% among beginners, but with **a slight loss of quality** among the most experienced. A 2026 field experiment then showed the limit: where AI **takes over** the conversation, customer ratings **get significantly worse**. The difference is not in the technology, but in whether the machine assists or replaces.

Measuring AI's Effect on Your Marketing

A research team measured how badly people misjudged their own speed-up when they worked with AI. The error averaged **39 percentage points**. That number is bigger than the effect you are trying to measure — which is why you need four metrics, not an impression.
