As much as I enjoy the new, non-“Classic” ChatGPT desktop app for Windows, some of its UX decisions are baffling. Software updates shouldn’t require a Myst-style pixel scrape to figure out what that tiny blue icon means or where I’m supposed to go next. Discoverability is part of usability.

I've taught tech since 1997. The job isn't knowing everything. It's knowing enough to serve the learner, knowing where your map ends, and never bluffing. Storytime: WINS, Kubernetes, rebuilding a course, and choosing learners over ego. youtu.be/LQpjSgUXQrc

Microsoft has 3 paths for building agents and most orgs pick wrong: 🔹 M365 Copilot agents = glorified custom GPTs 🔹 Copilot Studio = where real power lives 🔹 Azure Foundry = nuclear option They're layers, not competitors. Start low-code. youtu.be/3jZ_lzsgWTM
