Video Testimonials: Should I build?

Been playing around with some of the NEW AI video models this weekend including the 20second ones from LTX

https://testimonials.now/

Have a look at this (scroll down or hit examples). I think this is a good use for the 20s model. Gives plenty of time and room.

Anyway, should I offer these AI testimonials and build the rest of it?

I need feedback PH'ers!

Thanks in advance:)
