For comparison to how things are today:
- contacting vendors requires using the telephone, sitting on hold, talking to a person, possibly navigating the phone tree to reach the parts department
- it would need to understand redirection, so if call #1 says "not us, but Jimmy over at Foo Parts has it"
- finding the part requires understanding the difference between the actual part and an OEM compatible one
- ordering it would require finding the payment options they accept that intersect with those the caller has access to, which could include an existing account (p.o. or store credit)
- ordering it would require understanding "ok, it'll be ready in 30 minutes" or "it's on the shelf right now" type nuance
Now, all of those things are maybe achievable today, with the small asterisk that hallucinations are fatal to a process that needs to work
Today, a car repairshop might have a need for a custom software that will make their operations 20% more efficient. But they don't have nearly enough money to hire a software engineer to build it for them. With AI, it might be worth it for an engineer to actually do it.
Plenty of little examples like that where people/businesses have custom needs for software but the value isn't high enough.
