Even when going to a shop, I prefer to look into the options myself first. Explaining a salesperson what I need can take much more time, and then I am never sure if they just try to upsell, if I can explain my use case well etc. The only case where I opt for a salesperson first is when I cannot translate my use case to specification due to high degree of technical or other knowledge needed. I can imagine eg somebody who knows nothing about computers ask "I want a laptop, with good battery, I would use it for this and that", the same way they would ask a salesperson or a technical friend. But I cannot imagine using such an LLM to look for a table where I need it to fit measurements etc, or anything that is not inaccessible in terms of product knowledge. If I know the specifications, opting for an AI chatbot is inefficient. If not, it could help.
