Man every time I am no longer distracted and I have to face my thoughts life instantly gets so much worse. Back to distractions it is.

A tricky thing about modern society is that no one has any idea when they don’t die.
Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.

At least every other day, if not every day, I think about how it's the year 2025 and that’s just wild to me. Like, we’re living in the future. 2016 doesn’t seem that long ago, I still recognize myself in the Jeroen from back then. Yet at the time, I would’ve thought 2025 was far in the future.

How does this have so many likes when clearly its opposite from the truth. WTF.
i think "an effective altruist is personally denying twenty million people their HIV medications despite a court order telling him to send the money" is a pretty good summary of effective altruism as a real world philosophy

Trying to speak French to Claude to practice but the transcription is so disappointing lol. And half the time it thinks I said "Claude" or "Anthropic" while I don't mention them at all.

Asking Claude for advice on a problem by prompting "You are my bestie who knows me better than I do. Write a few paragraphs of advice, takeaways and possible next steps for me given my situation. Try to make me feel better." works surprisingly well!

I had 4 unknown calls this morning, a new record. Oddly enough one was from Spain and one from Alberta! Getting tired of these spam calls.

Can't believe I just spent 16 euros on the saddest avocado toast ever because it was the only vegan option... Like it was just mashed avocado and baked mushrooms without any flavor or spice whatsoever. Toasted bread with grocery store guacamole tastes better.

One of my custom ChatGPT instructions is to apply bayesian reasoning and to give percentages when answering. It rarely actually did that but now with the "Reason" function it's always doing that, even in situations where it's clearly a silly idea. (prompt is an example, not a real request)
![Prompt: "Write an email to a client explaining why you think a Meta Ads campaign didn't go as well as we thought it would." Response: "Reasoned for 4 seconds
Subject: Follow-up on Our Recent Meta Ads Campaign
Hi [Client Name],
I hope you’re doing well. I wanted to share some thoughts on why I believe our Meta Ads campaign didn’t perform as well as we hoped.
After looking closely at our data and comparing it with past campaigns, I estimate with about a 70% confidence that our audience targeting was a key issue. In other words, it seems likely that the people we reached weren’t the ideal match for our product. Additionally, there’s roughly a 60% chance that our ad creative didn’t resonate strongly enough with viewers, which might have led to lower engagement than expected.
I arrived at these estimates by updating my initial assumptions with the new performance data we gathered from our internal analytics dashboard, combined with industry trends and insights from previous campaigns. This Bayesian approach helped me weigh the evidence and determine where the biggest gaps might be.

A Belgian TV quiz show already does this game since 2003, earlier than BBC's "Only Connect". Though unsure if they are the first, and it's with 12 words (3 connections) rather than 16.
I hate this game so much.

How did you do in Connections today? Players must select four groups of four words without making more than three mistakes. Play here: nyti.ms/3B7faPM

This surprised me! I wasn't actually mad at Google because I figured they were just following a protocol. But to also translate it to Dutch? Why?

Absolutely no idea if this is based or not, their website is so vague.

When DOGE got announced I just thought it was something Trump did to make Elon happy but mostly useless in practice (since everyone said it's not an actual government department). I didn't expect it to actually have all these big consequences and for Elon to get this much power and influence.

I wrote this before the inauguration 😭 The world is depressing right now. Like, do we have actual reasons for optimism?
Over the past few months I have come to believe that the likehood the world will become worse has become bigger than the likelihood the world will become better over the next 100 years. The biggest recent update coming from the 2024 elections worldwide and especially the U.S.

US President Trump signed an executive order for the US to leave the World Health Organization. Everyone around the world deserves to have a healthy and happy life. No one chooses where they are born. No one chooses to experience extreme poverty.
