Codex is much worse than Anthropics model. My experience is that I burn 10x the tokens using Codex compared to Sonnet 4.6

It still fubars my code regularly at 11x the price. Github Copilot Agentic Mode + Sonnet 4.6 is stable and inexpensive.

It's a personal project, but inspired by OpenClaw (which I find way overhyped), I am building an ambient intelligence layer for investment finance including a 3-tiered memory architecture, sensors (for environment scanning), skills, reasoning agents, and a new agentic UI concept only for that purpose.

I wrote about it here: https://jdsemrau.substack.com/p/pair-programming-superbill-w...

Most "hackers" now are build to sell (i.e., micro-entrepreneurship), not build for intellectual curiosity.

Where did Fry's Electronics go? Where can I go an buy robot parts or even used tech parts?

Let's say I want to build a drone from scratch.

I reached the same conclusion. I tried using both for my personal investment ambient using agent-pair programming to build and agentic intelligence layer for stocks and the difference between the 2 models if astounding.

We need to bring back this culture.

It was a different company back then. The Internet was still new-ish and not the multi-trillion dollar company it is now. I'd think expectations are different.

This is about a crypto transaction leading to the Terra/Luna collapse.

If there is one benefit coming from crypto is that it explains clearly why finance is a regulated industry.

In that sense, at least for me, it was a third place where we could roam to get inspired and connect. We lost that. I was in Akihabara last weekend. And its the same in a way. While there are still a few, most tech stores are now phone/laptop stores that don't sell parts. Making the hunt for tech really boring.

What is interesting about OpenClaw is it's architecture. It is like an ambient intelligence layer. Other approaches up until now have been VSCode or Chromium based integrations into the PC layer.

Unlocked mature AI will win the adoption race. That's why I think China's models are better positioned.

I am building Agents for a long while now. The problem with Copilot is that it gets in the way too many times without being useful. Examples: When I open an email with 3 short lines of text, why do I need a "summary by copilot" button?

When I open a meeting invote from someone else the first 1/3rd of the screen is occupied with "Prepare for your meeting" nonsense. The "insights" button just provides general knowledge akin to "read the documentation".
