Not only that, but what you mentioned about katas, lately they're literally almost NEVER done and that's disappeared, sad but true

Back in the day at Codurance we did work on identifying conferences, making a clear distinction between conferences with in-depth topics and conferences that cover a lot of ground But with little detail; if the conferences that previously had depth now lack it, there is no differentiating factor.

If I wanted a technology conference, I'd go to one, not a crafting conference 🤦 I'm not going to pay for travel + hotel + tickets to see what I can see elsewhere, even on YouTube 🤦

What's wrong with crafters' conferences in Spain? Instead of talking about crafting, they talk about technology. The goal shouldn't be a mass conference or a conference for the majority, but rather to talk about what the conference is supposed to be about.

6/6 LLM agents can be powerful. They can help explore, draft, generate, and automate. But calling them an abstraction layer too quickly hides the real cost: verification, review, ownership, and responsibility. Sometimes a tool is just a tool. emmanuelvalverderamos.substack.com/p/agents-are...

Agents are not a new abstraction layer. They are a new place to hide the bill

LLM agentic development can be useful, but calling it an abstraction layer is how teams rename verification cost as progress.

5/6 If a tool forces you to understand its hidden quirks, model-specific behaviours, prompt sensitivities, or implementation details to use it safely, then it has not fully abstracted them away. That is closer to a leaky abstraction.

121

Emmanuel Valverde Ramos @emmanuelvalverde.dev · 29/06/2026

4/6 Abstraction is not: - automation - delegation - orchestration - compression - a black box - “it usually works” Those things can be useful. But usefulness is not abstraction

111

Emmanuel Valverde Ramos @emmanuelvalverde.dev · 29/06/2026

3/6 A good abstraction: - hides irrelevant details - preserves important semantics - exposes a clear contract - reduces knowledge consumers must carry - makes change safer

111

Emmanuel Valverde Ramos @emmanuelvalverde.dev · 29/06/2026

2/6 Abstraction is not just hiding complexity. It is building a model that lets us safely ignore details because the behaviour we depend on is stable enough to reason about.

111

Emmanuel Valverde Ramos @emmanuelvalverde.dev · 29/06/2026

1/6 People often say LLM agents are “just another abstraction layer.” I think that confuses abstraction with automation. A useful tool is not automatically an abstraction.

The problem is that people deciding if developers should be writing code are very often the ones who have never had enough experience with writing code to have a good idea what the value of writing code is and the purpose it serves, but they are convinced they know.

I'm so tired of the fact that when people learn OOP, they aren't taught essential concepts like the relationships between objects, so I've created this guide emmanuelvalverderamos.substack.com/p/how-object...

emmanuelvalverderamos.substack.com

How Objects Relate: A Practical Taxonomy for Object-Oriented Design

The problem is not the vocabulary. The problem is using one flat vocabulary for several different kinds of design decisions

Who knows? Maybe systems need to be designed, not just vibed? 🤷

The issue is that even with then It will go on the wrong direction. So I would say, LLMs are a tool use then wisely

I'm sick and tired of companies claiming they're more productive thanks to AI, so I've written a post to explain my opinion emmanuelvalverderamos.substack.com/p/the-produc...

emmanuelvalverderamos.substack.com

The Productivity mirage

Large Language Models can make the development subsystem faster. That does not mean the organization became more productive.

Parallel Change: how to evolve live systems without breaking consumers

Emmanuel Valverde Ramos @emmanuelvalverde.dev · 04/06/2026

The plan is restricted to reaching 100% coverage and not stopping until it reaches 100%. The LLM bypassing the restriction. What a great tool!

Lately there is so much noise about "Agile is dead because AI" So to replay once and just share always the same link: emmanuelvalverderamos.substack.com/p/ai-does-no...

emmanuelvalverderamos.substack.com

AI does not replace XP or Agile. It raises the cost of pretending.

AI can make teams more productive at producing code, and less effective at delivering value.

"Everyone is entitled to his own opinion, but not to his own facts."

Emmanuel Valverde Ramos @emmanuelvalverde.dev · 19/05/2026

I'm interested in this opinion; could you provide real-world examples of where this happens? On the other hand, I must emphasize that these are not metrics.

33/ Final punch line: Productivity means work was produced. Effectiveness means the right result was achieved. Efficiency means resources were used well. The best software teams do not just produce more. They produce the right work, with less waste.

010

Emmanuel Valverde Ramos @emmanuelvalverde.dev · 19/05/2026

32/ Software engineering needs sharper language. Productivity is not effectiveness. Effectiveness is not efficiency. Efficiency is not productivity. A strong team needs all three, but each one tells a different part of the truth.

211

Emmanuel Valverde Ramos @emmanuelvalverde.dev · 19/05/2026

31/ The real danger is using productivity as a moral word. “She is productive.” “This team is productive.” “That sprint was productive.” Maybe. But productive at what? For whom? At what cost? Toward what outcome? Without those answers, the word hides more than it explains.

100

Emmanuel Valverde Ramos @emmanuelvalverde.dev · 19/05/2026

30/ Good teams separate the questions. For productivity: What are we producing? For effectiveness: Why does this work matter? For efficiency: What waste exists in how we work? When the questions are mixed, the answers become vague.
