Love it!

Only problem is that now I want all things to have this level of UI

The good emotions come with the confidence in the engineering quality that it gives you as output (once you overcome the friction, which AI can help you big time to achieve).

This is a sub-case of the general one that is narrowing the interpretation of things. A big infinite amount of things can be true or false, only one can be a Rust variant.

Wait until you answer in "Ask HN: Who wants to be hired?" and start receiving hiring phishing emails.

Thanks for elaborating, I knew already what it is and is actually adequate architecture for some cases. I just complain at how is explained in an exclusive abstract level instead of an approachable dance of balancing definitions with real word examples to give our brains a break and let them breath bits of real world.

I really wish our culture to explain the applicability of the things we invent would be way way waaaay stronger.

Abstractions should be earned.

Not because executing them is expensive but because understanding them is.

Most beautiful computer syntax of the world.

Smalltalk is conceptual-centric in ways that are remarkably deep.

Pity our hardware architectures couldn't give us better hardware support.

Not that they didn't tried:

- Burroughs B5000 (1961)

- Intel iAPX 432 (1981–1986)

- BiiN project (1985–1990)

- Intel i960

- Rekursiv (Linn)

- jHISC ~2005

- MOOSS 2003

- Structural Object Processor (Xilinx)

The adventures they must be having and things they observed would feel unreal to us.

And of course I can't wait to have the cat translator. That's a big startup idea BTW, just a bit too early still.

    Location: Curitiba, Brazil (UTC−3)
    Remote: Yes (only) — 10+ years remote with US / Canada / EU teams
    Willing to relocate: No
    Technologies: Rust, agent harnesses / LLM product engineering (not research)

Looking for a remote mid or senior IC role with real ownership and preferably Rust-first backends. Distributed systems, fintech/crypto okay, AI infra / agent platforms; open to strong equity on early-stage. A record that matters: between 2009 and 2015 I was a tech founder. Last nine years, three different teams, three different tech stacks, zero production incidents on the high-scale systems I owned. Many of these from zero to prod.

A good explanation is not a fix but is a good starting point to a good diagnosis which is the foundation of a good fix.

The issue is when the calls and urgency are raised before making some mental space to even verify that there is enough clarity on what happen and these interrupt the clarification and remediation planning process.

Saying you shouldn't ask "Why did this happen?" and you should ask "What we're changing?" instead is wanting to jump the gun and pretend a required step doesn't exist.

It does exists, is just the executive anxiety reasonable in terms of wanting to be protective of the business but as protective as a family member of a patient wanting a good outcome from the surgeon during the surgery.

Only worst because the surgeon's boss is this anxious family member, and she has a laboral gun pointing to the doctor's neck.

You covered design intent now. That made it a great answer, thanks.

Can you add a "why?" / "why now?" section? Don't be another project that is a bunch of how that is leaving out to explain why it exists or exemplify what classes of problems it unlocks solutions for (applicability).
