The best designers are exceptional systems thinkers, which makes them dangerous product builders in 2026.

2025 was like the first season of a sci-fi show: Just there to orient us in this weird new world. 2026 is season 2, when the story really gets going.

This was my first use of Design OS on a real, shipped app. Took about 7 work days start-finish. Smoothest design- to-build process I've done yet. Full walkthrough of the process is available inside Builder Methods Pro.

Reading every response is impossible. Missing important ones is expensive. So I built InboxSummaries: It reads my incoming surveys, etc. and surfaces insights, trends and opportunities I'd otherwise miss. Using it daily now. Should I open it up?

Really want to see a smoother hand-off between Claude Code and Claude projects. I constantly move between the two (Claude for ideating and planning and Claude Code for building).

I find Opus 4.5 is excellent both in Claude Code and in Cursor's Agent mode. I use both regularly. Claude Code for big, autonomous tasks. Cursor agent when I'm working with agent more collaboratively through a problem or design tweaks.

Me: "I'm shopping for AI." Google: "We got you. Try Gemini. Or AI Studio. Or Labs. Or Nano Banana. Wait, Nano Banana Pro. Also Imagen. No, ImageFX. Actually Whisk. Or Flow. Or Veo. MusicFX. TextFX. Chirp. Or... (wait there's more...)"

AI inability to actually *see* video and *hear* audio is a big blocker to it truly replacing pro human video/audio editors. AI can *generate* new audio/video, but can't see/hear/edit existing audio/video content. That's at the top of my wishlist for 2026 breakthroughs.

Quite a year of building. 303 days. Lots of Claude models. Dabbled with GPT-5 and Composer. ~50/50 Claude Code & Cursor. And apparently I like to ship on Fridays ;)

Micro-managing an AI agent can work. Telling AI your end goal and letting it propose good options is much better. Directing AI on how to fix something can work. Sharing your impressions (good/bad) and trusting it to dial in its next version is much better.

The downfall of the Album is the worst thing about today's new music. Enough with the singles and 3-song EPs. Give me an hour+ of your best cuts from a multi-month creative bender in the studio.

There are still (and always will be) world-class, experienced, highly technical, creative thinkers behind the world's best automobiles. But those people are not assembling the cars by hand. Robots do that.
