I had to buy a camera lens recently. Not through an AI. Through Amazon. I opened a browser, navigated to amazon.com, logged in, went to my order history, scrolled until I found the last lens I bought to confirm the mount type, went back to search, typed a query, filtered by prime shipping, read four product pages with conflicting spec tables, checked a compatibility thread on a photography forum, went back to Amazon, added the item to cart, entered my address for the fifth time this year, and confirmed the order.
