Similar to that thinking, I made a previous comment how many developers in the "L.O.B. Line-Of-Business / CRUD" group are not familiar with "algorithms engineering" type of programming: https://news.ycombinator.com/item?id=12078147

Vibe coding is easiest for CRUD apps. However, it's useless for developing new scientific/engineering code for new system architectures that require combining algorithms & data structures in novel ways that Claude Code has no examples for.

About 75% of the time the code snippets it provided did what it said they did. But the other 25% was killer. Luckily I made a visualization system and was able to see when it made mistakes, but I think if I had tried to vibe code this months ago I'd still be trying.

(These were things like "how can I detect if an arbitrary small circle arc on a unit sphere intersects a circle of arbitrary size projected onto the surface of the unit sphere". With the right MATLAB setup this was easy to visualize and check; but I'm quite convinced it would have taken me a lot longer to understand the geometry and come up with the equations myself than it actually took me to complete the tool)

One my standard coding tests for LLM is a spherical geometry problem, a near-triangle with all three corners being 90 degrees.

Until GPT-5, no model got it right, they only operated in the space of a euclidian projection; perhaps notably, while GPT-5 did get it right, it did so by writing and running a python script that imported a suitable library, not with its own world model.

I work on a vision based traffic monitoring system, and modelling the idea of traffic and events goes into so much complexity without a word of code written

These people are working on problems that have tutorials online and dont know that someone had to make all that
