"AI will replace engineers" misses what engineering actually is.

Writing code = generating primitives. That's the commodity.

Engineering = composing primitives under constraints: consistency vs availability, cost vs reliability, flexibility vs simplicity.

Built a system that doesn’t “generate answers.”
It runs experiments, measures results, and keeps only what works.

A classic LeetCode hard problem is "Merge k Sorted Lists" (Problem #23), which involves merging sorted linked lists into one sorted list.

Here’s the improvement :
• 5.8x faster (21.5ms → 3.7ms)
• 11 experiments → 3 real improvements
• everything else rejected (+1 crash)

Clear progression:
algorithm → inlining → branch tightening

Less noise. More structure.

I built something in between:

• Transparent scoring (tech + fundamental + sentiment)

• Clear signals
• AI synthesis (what’s happening + why it matters)

• Playbook to actually use it

Since OpenClaw is a game changer in many ways, I wanted to understand how it worked under the hood. Here’s a detailed analysis of architectural patterns and innovations in the OpenClaw project: https://t.co/qs77mAkDXp Exciting times ahead.

The nature and purpose of software and the way it’s built is changing at an unprecedented pace. Understanding how things actually work is increasingly important. I prototyped https://t.co/olz59g8unW to help accelerate the understanding of unfamiliar open source code bases.

[Gautam Kulkarni @gskulkarni]

@joshclemm Completely agree. More domains now seem to align more with how our brains work.

@karpathy This app helps with a deep analysis of any given open source project and can be used to extract insights, identify problems, suggest improvements, etc. https://t.co/fRbeX5xOCi

@paulg @garrytan Reminds of the lazy weatherman problem in Tom Cover’s Information Theory textbook.

[Gautam Kulkarni @gskulkarni]

@karpathy Highly recommend reading Mahabharat, Ramayan and associated literature. You will see a lot of societal complexity, character development and interconnected legends. All of which were written several millennia ago.

[Gautam Kulkarni @gskulkarni]

@martin_casado This is why I don’t use Perplexity or equivalents - they are very easy to vibe build and then we can customize them to our needs.

[Gautam Kulkarni @gskulkarni]

@joshclemm And no frameworks used, keeping it simple and easier to debug.

@rohindhar What about condos with parking in places like Pac Heights or the Marina?

@rohindhar The fire risk of 12% is unacceptably high

@AravSrinivas @AskPerplexity The probability of any batsman scoring a century in any specific match is very low.
