@exedev Super interesting read. How do junior devs learn under this model though? Pre LLMs you’d learn the fundamentals by doing things like this by hand, over and over. But now that everyone is expected to operate at a higher level of abstraction, how are junior devs supposed to learn?

Imagine making 570k a year and then hearing your own CEO say AI might handle most coding within a year

Most people jump to extremes either engineering is dead or this is all hype. Reality is less dramatic honestly more practical

AI is getting very good at producing code especially repetitive work and standard patterns. That reduces the time humans spend typing that part is already happening you can see it everywhere

But large systems are not just code. They are decisions layered over time architecture choices trade offs between speed and reliability cost constraints legacy constraints security concerns none of that disappears just because a model can autocomplete faster

When something fails in production its rarely a syntax mistake its assumptions its how components behave under load its edge cases nobody modeled clearly and that still requires experienced judgment

So yes parts of the job are being compressed especially low leverage implementation work

But higher leverage thinking system design accountability those are not automated in the same way at least not today

If someone’s value is mostly writing standard code quickly the pressure is real.
If their value is understanding systems deeply making good decisions under uncertainty that still compounds

The job is changing its not disappearing

@fluffypony @ns123abc Startups are a bundle, everyone is better off that way. These type of arrangements break the bundle and makes us worse off in the long term https://t.co/cHrqQCPEBX

I visit Madrid several times a year. Every time I'm back, it feels more open and buzzing with energy.

London and Paris had better watch out: a new global European metropolis is emerging fast.

@EMTmadrid Buenas! donde puedo encontrar los datos GTFS-RT de los buses de Madrid? Google Maps ya los está usando, pero no los encuentro en el portal de datos de EMT. Solo veo GTFS, no los GTFS-RT que tienen el estado en tiempo real

@ole_b_peters When is it coming out 👀

I’m excited to announce a new feature-length documentary project I’m working on with my co-director @apoolos about Russia’s efforts to eradicate Evangelical Christians from the map of Ukraine to impose Russian Orthodoxy as the state religion.

About that debate on assumptions in economic theory:

@shl Care to elaborate? Genuinely curious

@michaelreid52 @TheEconomist Always a pleasure to read you!

@kilkenomics hi, are the lectures being streamed or recorded?

Just found out that the Manx version of the name "Juan" is just that, "Juan" but pronounced with a standard English accent

The ironic twist of the stabbing of Salman Rushdie is that I've never heard about Satanic Verses before and now it's next on my reading list

@pyquantnews Not a good resource. You can't just run a test to check if the price movements of a stock follow a normal distribution. This environment is strictly fat tailed.

@jammastergirish Looking forward to this!
