I build software for contractors (plumbers, electricians, HVAC repair, etc) and they're some of the fastest adopters of these systems. I believe YC has even invested in a few.
Regarding the AI receptionists, from the calls I've listened to, there's still a bit of the uncanny valley/overlapping speech issues that I'm unsure are ever fixable just due to latency.
But for low margin businesses like contracting and (I imagine) auto repair where labor is your most expensive cost, these owners are doing anything they can to reduce their overhead.
I think the opposite is true. Sure, it's technically impressive, but users have been trained for decades at this point to understand how a basic marketing page should look and this isn't it. These kinds of sites are best left as portfolio pages for designers to show off their skills, not for B2B SaaS landing pages.
