Its not a case of "trendy standards" as much as an evolution. Just as we had 500MB hard drives running at 5400 RPM 20 years ago, that's considered junk today. You can get terrabyte solid state drives that store 2000 times the data and access it 200 times faster.
Firewire and USB2 are 2002 technology. Firewire had two iterations, 400Mbps and 800Mbps. USB 2 is 480Mbps, and USB 3.1 (2013) jumped to 10Gbps. Thunderbolt was designed to handle even higher data rates. Current Thunderbolt 3 is 40Gbps capable using multiple channels. USB4 standards were adopted in 2019 and were included in the Thunderbolt 3.
Dante is an ethernet IP based audio system. While you can do Dante via software, this requires significant processing at each node, which results in latency. To do things properly, you need to go with proprietary hardware based Dante equipment. You can buy Dante devices from lots of companies, but they ALL must use Audinate's chips for the implementation of the system.
Dante is great for accessing multiple devices and has lots of capacity for handling audio, you can send data directly from your computer to a active speaker system all over ethernet cable. It tends to be more pricey than Thunderbolt or USB devices. You are locked into a single supplier which carries some risk.
Thunderbolt and USB are essentially open standards now, so implementation should be more widespread. Windows PC have been slow to implement Thunderbolt, but those chips are becoming more common on motherboards. Its already in Apple Macs. USB4/Thunderbolt 3 is now being implemented on AMD processors. It's simply a more capable protocol than USB2.
