Making a USB 3.0 or Thunderbolt device which doesn't kill WiFi when they are working together is really, really challenging, but still possible in practice. Things can go as extreme as covering the entire USB 3.0 lane on the PCB with a solid RF shield from the chip, to the connector. Things such as above preclude any chance at USB 3.0 getting into cheaper product niches. I once looked for a good USB 3.0 testbench laptop to test devices with, but found out that laptops themselves have terrible USB 3.0 RF isolation. I went through many laptops of reputable brands, but the only laptop I seen where USB 3.0, and WiFi were working flawlessly was a very old Sony laptop from 2010.
