USB 4.0 Will Arrive In Late 2020
Yeah, you just got used to USB 3.0, 3.1 and recently 3.2 right? It has been a confusing mess with the renamed denominators alright. But basically, the USB Promoter Group is finalizing the specifications of the new standard USB 4.0, the first products are expected in 2020.
The USB 4.0 Spec is at revision 0.7 and the USB Promoter Group will finalize it in a month or so with some availability in 2020. Guess what? It is based on Intel's Thunderbolt 3 technology and that achieves per at up to 40Gbit/s.
So that would be doubling up on the current fastest standard at 20 Gbit/s (USB 3.2 2x2). The USB Promoter Group) finds the differences so big that they are considering to create a new USB logo for it. USB 4 would be backward compatible with existing devices with USB 3.2, USB 2.0 as well as Thunderbolt 3. The new standard also adapts support on protocols like display port over Thunderbolt 3.

People have gotten very used to their "long" charging and data cables. This may upset those who are not willing to go back to shorter cables for quick charging or fast data rates. USB 3.1/2 already has issues with cables longer than 3 feet, and Thunderbolt 3 has similar issues, especially when sending display data. Maybe they should have concentrated on this part before just jumping to the nearest speed hike.

Intel clowns, both USB and PCIE groups, some big money is going on to discredit the launch of AMD right now.
PCIE 5 and USB 4, so everything on this launch feels outdated.
And just to bring some ground, most cable makers are having a hard time to make even 3.1gen 2 cables to the standard, right now, some very few brands, including Apple, can produce decent cables. Now, imagine guys, every device compatible with USB4 will need an ultra expensive cable... Most people haven't even saturated the USB 3.0 standard with their devices...

I'm growing less and less fond of USB's trends ever since type C came out. Not that I have any gripes with the type C connector, just everything else associated with it. USB is turning into some really poorly thought out all-purpose connector. Yeah I get it, it's supposed to be universal, but being universal doesn't have to mean being a jack of all trades. What made USB 1.x to 3.0 so great is how it was consistent. You knew exactly what you were getting, it was very cheap, and very reliable. It might not have had such a wide array of functions, but at least it was user-friendly (aside from some people struggling to find which side was up and which one was down).
Now, it's turned into something where you can see a type C port and have no clue what it'll give you. Sometimes it can charge/power devices, sometimes it can't. Sometimes it'll offer 40Gbps, sometimes it'll give you 5Gbps. Sometimes it's a Thunderbolt port, sometimes it isn't. Sometimes it has the DP specs, sometimes it doesn't. Sometimes you can daisy-chain, sometimes you can't. The cable you use can affect functionality. The host device you use can affect functionality.
I can't imagine all of the security risks and electrical gremlins that'll be involved by getting closer and closer to the PCIe bus.
USB has been distorted into something ugly and user-unfriendly.

USB Promoter Group is a clown club.
