A test told an AI model everything it could not do: no logging in, no creating accounts, no entering personal information, no making purchases, nothing destructive.

The AI agent that lists my eBay items can group my photos, identify the item, price it from comps I hand it, and build the listing. It can’t open its own eBay developer account. eBay wants a person for that, and for a few more screens after it. So this eBay API setup guide splits … Read more
I write software for a living, mostly small mobile games. Last week I was also setting up a Windows machine at a site I can only reach over the network. The site is a three-day trip away for me, so everything I do there happens through a remote session. On Saturday morning I was in … Read more

I have read countless posts about bloated marketing roles where six jobs are crammed into one title. One listing asked for a “Marketing Manager” to handle brand strategy, paid media, SEO, email marketing, copywriting, and front-end web design. All of that… on a junior salary! These are not rare. They are the norm these days. … Read more

One year ago I wrote Breaking Free from Xcode: Unlock AI’s Full Potential in iOS.

AI changes different organizational boundaries in different ways. AI-native is often treated as shorthand for flatter teams, fewer people, and fewer boundaries. That confuses what AI can do with what an organization should become. I do not think companies are moving toward one final “AI-native” organizational model. Some boundaries exist because people cannot carry enough … Read more

Most talk about verifiable AI is about the model: proofs of inference, attested hardware, reproducible weights. That matters.
