This is the consequence of the majority compulsion to communicate in language figures as opposed to concepts.

It's human to do that because it's too dry and unwelcoming to talk in precise concepts disregarding any cognitive friendliness, not to mention do that all the time.

A computer programming in any high level language is concept talking all the time and only us nerds like it :D

Not even that as we form tribes with preferences to one or other computer lang.

Now we're talking less to each other and AI is going to influence us to invent a trillion things that will make understanding diverge and start to become scarce.

AI removed the fun even to this.

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.

There is so much information in this opinion...

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.

This is the new BS generator, but more useful

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.

Love it. And thanks for the refreshing skeumorphism

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.
