Comcast quoted rates in this range for installations in areas near Palo Alto. IIRC my friend was quoted $20k for the installation. She might have gone for it if they'd charged $5/mo after that, but of course Comcast wouldn't be so kind. Last I heard, she was still on AT&T copper. Hopefully Starlink will be able to help people like this, who are just outside the reach of existing wired internet.
