The worst conversations in commercial software development are planning conversations that take longer to occur than a quick spike would to materialise.
Do the work, don't talk, for all of this category of things.

I will never forget my old lead designer at Turbine, Chris Clay, who had a rule:
Never spend more time talking about a design in a meeting than it would take to prototype it and see.
I was in plenty of meetings where he suddenly slapped the table and invoked Clay's Law

I'm gonna miss RedEngine with the UE transition in CDPR games. Legitimately a feat of engineering.
mini rant: no, elevators in cyberpunk are not 'cleverly concealed loading screens'. you really think you can traverse whole city and enter a huge complex interior with no loading screens but we need to do elevator tricks to load a penthouse?

NoAI - "Not Only AI"
Capture the idea that products that are only AI are doomed to produce slop, because statistical models need to be systemised, surrounded with traditional programming and ancillary techniques to be good and useful.
Claude Code is a "NoAI" system, Copilot Agents, similarly.

In retrospect it was quite a weird period to be a human where you could watch the real-time development of a distributed culture. That probably hadn't happened before just because of pure timing.
But I was a teenager so absolutely did not understand that was what was happening at the time.

Keep seeing this headline as if it's some kinda "lol everything is broken" when the buried lede is that there's clearly been an error in the XAML layout engine, at a guess, related to GPU acceleration, and literally everything in WinUI uses that?
