One email a day on where software breaks. Written in Spanish.

The emails are in Spanish. If you read Spanish, keep going. If not, the talks and papers are in English.

For the last couple of years everyone has been asked to put AI into what they build. An assistant here, a plug-in there, a chat on top of the customer data. It works in the demo. Then the first bad day arrives: someone types what they should not, or by the tenth message it answers as if it never read the previous nine, or it does something nobody asked with a permission nobody remembers granting.

That has an explanation. Almost everything that breaks does, and it is rarely in the new tool. I have spent twenty years opening systems their owners considered closed: medical records of millions of people sitting open on the internet, back doors that had been inside company systems for months, an eight hour job that dropped to a tenth of a second once someone looked at where the time went. Later I was the technical lead of the AI team at a bank with 185,000 employees. Now I work on my own, inside companies, with the system running.

What I see there on a Tuesday, you read on Wednesday. No names, the whole failure.

When you sign up you get a ten minute audio, also in Spanish, on why ChatGPT, Claude or whichever model you use starts brilliant and turns dumb around the sixth message. It has an explanation and a fix, and almost nobody who uses these tools every day knows it.

Every day? Yes, I send one every day. It takes three minutes to read. The day it does not interest you, delete it.

Will you sell me something? Sometimes. Training and consulting, which is what I live on. I say so when it applies and do not dress it up as advice.

And if I do not like it? You unsubscribe with one click.
