AI chats have become so slow.
The initial response is slow and most of the times they have to "think longer" to get an answer even for basic queries.
I don't like this direction we are headed.

Developer anxiety is actually a quality control mechanism. It makes us check edge cases and side effects.
LLMs aren't dangerous because they're wrong, but because they're fearless. They write terrifying code with zero hesitation.
Beware of what you approve. You are the only guardrail left.

"The night before, at the speaker dinner, I confessed to Adrian, the conference organizer, that fitting everything into 30 minutes felt impossible. Could I have just a bit more time? He smiled and shook his head. "Cut more slides. You'll only be left with the great ones."

Cascadia Code at 15px is the go-to fixed-width font for me. It has been for years.
The characters are "square" and bulky enough for easy scanning 🙌

Breadcrumb separators belong in CSS, not HTML. Just use the `::after` pseudo-element.
nav > ol > li:not(:last-child)::after {
content: " / ";
color: lightgray;
padding: 0 0.5em;
}
The `:not(:last-child)` ensures no trailing separator after the final item.

Throttling the network in Chrome DevTools might not do what you think it does!
Depending on how the network is throttled you'll see different loading behavior and different metrics.
