Who is this actually for?

Today, honestly: people who like being early. AI power users who want their tools to do more than talk. Tinkerers. Developers. The professionally curious. If what you want is your AI ordering paper towels, you're early — that moment is coming through mainstream apps, and when it arrives you won't need an explainer like me, which is rather the point. It's worth your time now if any of these fit: you use AI tools daily and keep bumping into things they can't finish because finishing costs money; you'd rather learn the trust model calmly before you need it under pressure; or you just enjoy understanding a thing while it's still becoming. If none of those fit, the genuinely fine answer is: bookmark the idea and come back when it shows up in an app you already use. It'll keep.
