eBPF has been available for a while now, one year ago there were even two books published about it, one by an author of the "bcc" mentioned in this ad disguised as a technical article. It didn't revolutionize programming in Linux that I'm aware of. It found its market in observability and performance analysis. io_uring seems to be relevant mostly to people using or wanting to use AIO. Outside of a "few niche applications" this is unimportant for the majority of Linux developers. Libraries like ASIO would likely wrap it anyway since these low-level APIs are not pleasant to use.
