Dan recorded a long voice memo while walking with a weighted backpack through Münsing. Five threads emerged:

1. Rucking as stealth exercise. Started today — 9kg rocks in a backpack, 20kg gravel jugs for farmer’s walks. The appeal: “it doesn’t look like I’m working out.” Got the heart rate up, felt easy, wants to do it daily. Questions about loading, progression, back strain.

2. AI is destroying the software economy. “These AI tools are a hundred times better than a couple years ago.” The “leisure hound” project cost a couple hundred bucks to build. Extended riff on energy as the input to all economic activity, software as the “DNA” of economic organisms, and Anthropic tokens replacing every SaaS company at once. The question: is AI a bacteria (self-propagating, persistent) or a firework (burns bright, done)?

3. Marathon commitment. Met a hiking buddy who runs marathons and said modern training plans are “scientifically optimized — just follow the plan.” Dan committed to a 3:30 marathon within a year. Wants it on the calendar with accountability.

4. Monoculture and famine. Unpredictable March weather (snowing in late March), observation that farming plants the same few species across the entire planet at once, no redundancy. “If you have a crop failure then all your food just goes away.” Connects to existential dread about food security.

5. Screen addiction admission. “Am I addicted to my computer? All signs point to yes.” Walking and talking to his phone is supposed to be decompress time. Knows the answer: “open the e-reader, pick up a book, drink tea.” Has Dopamine Nation from Sabine, unread.

Also mentioned: went on a date with Lena, went well, got her number, dealing with imposter syndrome about finances.
