Plus, I've been reading all the interesting articles from @edzitron.com about the GenAI bubble.

This is not financial advice.

In January, I sold my Tesla shares.

Today I just did the same with some NVIDIA shares I bought years ago.

The reason is the same: financial benefits are less important than moral stances.

Wrote about a couple of unrelated topics lately, both quite personal.

A Humbling Experience, Lessons Learned, and Adventures in Self-Hosting

How a recent hubmling experience helped me identify a major gap, and why I'm going all in with self-hosting my own services.

I've written about this insane tendency a few months ago: makemeacto.substack.com/p/accelerati...

Accelerating drift into failure: today's most widespread "AI Strategy"

What can go wrong when the CEO pushes technical decisions, shift focus from users' problems to unreliable technical capabilities, and try to persuade everyone else to follow suit?

My video about how LLMs are not search engines has led to many, MANY comments telling me that I should be using Perplexity. Some insisting that Perplexity does not hallucinate.

Out of a list of 26 papers it just provided me (in "Research" mode) 4 were real. FOUR. 85% hallucination rate.

Deploying from your IDE (and ignoring years of good practices) is a bug, not a feature.

Yet, most vibe-coding "products" keep encouraging such stupid practices, motivated by myopic growth calculations.

Deploying from your IDE is a bug, not a feature

Turning an anti-pattern into an easily accessible feature makes it worse, not better.

What a perfect manual of bad management!

Besides what everybody mentioned (going rogue, meeting on Saturday), one extra subtle piece stands out.

He should have consulted people to survey their views before taking such a "bold" decision, not as an afterthought once faced with resistance.

@bcmerchant.bsky.social I guess this promo doesn't apply to any of the current yearly subscribers?

Any other way to get a signed copy of The One Device?

Currently reading Blood in the Machine, loving it, and curious about your other books!

A community member recently shared a dilemma he faced.

Hire the expert software engineer, cautious about AI, or the AI enthusiast with big gaps in CS fundamentals and reasoning abilities?

My default rule: the expert SWE. I explain why in today's article.

Expertise vs AI proficiency: a hiring dilemma

A true story dilemma: Who do you hire? The seasoned expert with deep domain knowledge who is hesitant about AI, or the junior, AI-native enthusiast who may lack fundamental skills?

Just read this awesome article from @edzitron.com

I would feel better if I knew he was wrong, but I'm afraid he might be right.

I'd love for someone in the "optimist" camp to come up with an equally detailed analysis.

Not counting on it anytime soon.

Another brilliant and depressing article from Brian Merchant.

The closing reminded me of the excellent TED talk by @scott.hanselman.com , particularly the part on people reporting having fewer and fewer close friends.

When I coined the term "digital cocaine" back in February, I was not expecting the analogy to turn out so accurate.

Is GenAI Digital Cocaine?

How a recent common frustrating experience with AI-assisted tools let me to a deeper reflection on the impacts of overreliance on such crutches.

Visionaries, Rebels and Machines by Jamie Dobson, highly recommended

My 2 favorite things about this recent summer break:

1. I skipped a few weeks of AI hype online content and didn't miss it for a second

2. I read a bunch of good books.

If you're interested in 2, you can read up on my latest post: makemeacto.substack.com/p/books-i-re...
