I recall this article on QUIC disadvantages: https://www.reddit.com/r/programming/comments/1g7vv66/quic_i...

Seems like this is a step in the right direction to resole some of those issues. I suppose nothing is preventing it from getting hardware support in future network cards as well.

QUIC does not work very well for use cases like machine-to-machine traffic. However most of traffic in Internet today is from mobile phones to servers and it is were QUIC and HTTP 3 shine.

For other use cases we can keep using TCP.

Let me try providing a different perspective based on experience. QUIC works amazingly well for _some_ kinds of machine to machine traffic.

ssh3, based on QUIC is quicker at dropping into a shell compared to ssh. The latency difference was clearly visible.

QUIC with the unreliable dgram extension is also a great way to implement port forwarding over ssh. Tunneling one reliable transport over another hides the packer losses in the upper layer.

Why doesn't QUIC work well for machine-to-machine traffic ? Is it due to the lack of offloads/optimizations for TCP and machine-to-machine traffic tend to me high volume/high rate ?

I don't understand what you mean by "machine-to-machine" if a phone (a machine) talking to a server (a machine) is not machine-to-machine.
