Some seasons are about output. Others are about everything that has to happen first. I’ve been quiet for a bit. Still here. Still building. More soon.

Question for my network: Has anyone been to one of the recent Meet with #Apple Workshops around the new design system? - What's it like? (format, sessions, etc) - Is it required to go all 3 days? - What was the biggest take-away for you and your team? developer.apple.com/events/v…

Played with Foundation Models from this years #WWDC25 and I’m EXTREMELY impressed! One thing I’m curious about: how long has an average response been taking on your system? I’ve been sitting somewhere around 11.2 seconds.
