what does the following mean?

USB4 doubles speeds compared to today's fastest USB 3.2 by incorporating Intel's speedy Thunderbolt technology

Although USB4 benefits from the Thunderbolt technology infusion, there's no guarantee the two technologies will get along. For example, today's Thunderbolt 3 uses a laptop's USB-C ports, but a USB4 port a couple of years from now won't necessarily support a Thunderbolt peripheral. Thunderbolt 3 is an "optional capability" for USB4, meaning that device makers will have to clear Thunderbolt's testing and certification requirements.

USB, will get better in 2020 with a Thunderbolt technology infusion. But Intel has plans to improve Thunderbolt, too.

USB 4, in the last stages of standardization now and due to arrive in products in late 2020 or so, is incorporating Thunderbolt 3 technology. That'll not only double its maximum speed to 40Gbps but also give it flexibility missing from USB 3, like the ability to intermix time-sensitive video data for monitors with other information. That should also increase the utility of USB hubs and docking stations, too.

It quite sounds like USB4 and TB3 (? or 4?) are getting more and more similar: port, functionality, speed.

What am I missing here?
