to buy a toilet paper, you have to click 2-3 buttons or type out toilet paper in a search bar and hit a button. and then you have to scroll around, hit more buttons, filter, sort, then click through to the product page, review details, add it to your cart, start the checkout and select a payment method, confirm the order, and purchase.

compared to prompts:

"Show me toilet paper that has good reviews for being soft and that doesn't clog"

"I'll buy the first option, just use the card I used last time for payment"

What saves time with an LLM is being able to communicate what you want in natural language. with the normal experience, you're pressing lots of buttons and other inputs to get some results so you figure it out yourself. You will get results, and you will pick what you think is the best option for you (but chances are it isn't, since the site didn't know exactly what you wanted).
