let me change my mind about this

It’s rare that anyone but “Principal” and “Distinguished” “Engineers” decide on the stacks in enterprises. Given these roles are usually tied to director and VP level pay scales, there’s exceedingly few compared to all those resumes in your bin. “Doing your job” is often suboptimal.

Maybe.

My mental model for UIs is rooted in physical metaphors: steering wheel, speed gauge, light switch, faucets, doors, etc etc and these things don’t make sense as caches in my brain.

it’s maybe the difference between *views* and *controls*

Idk, thanks for the discussion!

The settings are orthogonal to the real-time network speed, which (in the example) is the purpose of this UI. This is not so different from waveform in a DAW or a video playing on YouTube.

Point being, a lot of UI just isn’t a cached of data, it’s more like a stream of data.

fair. Ideally if you fail to declare one of the expected states, the runtime would inform you via error/warning

One that comes to mind is fast.com

Obviously this is somewhat trivial but it’s a utility that I personally use regularly that has a good UI and doesn’t strike me as a cache of data. Any sort of “real-time” stream of data fails to fit this mental model of a cache

It’s a terse mental model but not a useful one. This is a server-centric view of UI. This idea doesn’t extend well to a strictly local app or a highly interactive app where interactions are ephemeral and the UI state is not persisted

<use-async key=comments>
<p slot=pending>Loading…</p>
<p slot=rejected class=error>
Failed to load.

</use-async>

Would love a web component version of this! Nice work 👏

This is really cool! Your suggestion for Rust/Haskell makes sense. I’m curious your thoughts on using Typescript with a really strict config as the base lang, given how prevalent it is in frontend applications?

Even worse: the longer this is the case, the higher the skill floor is, eating into mid and senior level roles until we’re only left with “distinguished wizard architects” and their fancy autocomplete
