But I used to work with a lot of b2b salesman. Yeah a lot of the products I bought were expensive but one reason for that was the sales people. Often they would come to my company, setup a demo using our products to confirm they would work as intended, when delivered they would be present to verify proper setup and operation. About the only part an Ai might be able to do is help in selection of proper options for your application, for example on a computerized microscope if you're looking for small features it's sometimes better to get B&W camera instead of color as it can detect smaller differences in contrast between two areas. Maybe an Ai could potentially determine and recommend that(not with current tech but in the future maybe) but every other aspect of technical b2b sales would be impossible.
