The only person I've encountered recently that had a legitimate actual need for multi-gigabit wireless and internet access works on cleaning up LIDAR data from construction site scans. Maybe if you're editing a lot of video content, but people doing that tend to benefit more from fast local storage during the editing process.

End-user wise the only customer I've had that sustained a gigabit transfer rate for multiple days was doing something stupid: they uploaded their 20 TB NAS to a backup service, reformated the unit, then downloaded it. They could have done an in place filesystem conversion cheaper and way faster, but they chose an option in the idiot realm instead. I'm guessing they don't have backups of their data and will be very disappointed when one of the HDDs dies.
