If LLMs become the "best way to produce software", we will need open alternatives or alternatives made in the Global South. I just saw a post where someone spend 5 USD on a problem. 5 USD is a lot of money in the Global South.

If it’s a nothing burger: Are we headed for a global recession if the bubble pops? All that investment came out of somewhere! The world’s largest economy is not in a recession because of 5 companies??

I need a drink. Rant over 😊

I get that everyone thinks they lived through a major shift/transition … but boy is this one insane.

If AI hypers are right: the gap between haves and have-nots grows exponentially (assuming capitalism stays as is and does not evolve)

If AI doomers are right: LMICs are now just resource farms

Absolutely! It’s crazy because you could argue that running your own open alternative is more expensive (in the short/mid term at least) than the $5.

A bigger issue is if we lose problem solvers to LLMs, and develop a dependency, global south is F’d when the VC money stops and $5 is actually $300

Computational Mechanisms of Self-Enhancement During Social Comparison and Their Relationship to Internalizing Symptoms - Moriah S. Stendel, John A. Clithero, Robert S. Chavez, 2026 Internalizing disorders, such as anxiety and depression, commonly feature cognitive biases in self-evaluation, particularly in the context of social comparison....

Excited to share our latest paper on computational mechanisms of self-enhancement with links to mental health. We used hierarchical Bayesian drift diffusion modeling to decompose choices on a social comparison task and relate them internalizing symptoms.

I’m struggling to get reliable street level env air quality data - Working on health+env models with clinics serving unhoused populations and recently learned that they are often kicked out of their neighborhoods and only return for clinic days … not sure where to start … help?

It’s not hyperbolic to say AI is a multiplier. A multiplier multiplies. I’m seeing more people just getting better are “meta-work” and large volumes of mediocre work.

If you don’t know where you are going you will just go further in random directions. The real problems don’t go away.

When using LLMs, it's very important to give clear instructions. Spec-driven development is the future.

For example, a clear prompt to add two numbers could look like:
ADD a TO b
ON SIZE ERROR
DISPLAY "Error"

This specifies the overflow as well.

@todoist.com , can we get description for projects? This could be a game changer! Often projects need a short description (or a long one), and we have to put it in a doc elsewhere… and have to juggle tools.

I wouldn’t need google docs for project spec documents, my team can just live in Todoist!

Writing is thinking

Outsourcing the entire task of writing to LLMs will deprive us of the essential creative task of interpreting our findings and generating a deeper theoretical understanding of the world.

I'm convinced understanding Geometric #Algebra requires unlearning almost *everything* from years of Linear Algebra exposure.

My brain is actively rejecting GA - especially in applications.

This transition in thinking frameworks is worse that when I gave up Frequentism for the church of #bayes.

It feels like eating but not getting satiated, and feeling more empty.

But it’s a great business because it’s much harder to work without it after using it - skill loss is 100x easier than skill gain. Feels like for the first time ever neural plasticity is a handicap
