Yeah. Alternatives to long-established and useful technologies have to meet a high bar before their option pays for their disruption.

Things that seem potentially worth it to me:

* seL4

* Google's SQL syntax tweak

* Rust

* GraalVM

* systemd

* Tree sitter

* LSP

* CMake

* Bazel

These all get you a step change improvement in comprehensibility, safety, or something else important.

Things that seem like more churn than they're worth:

* Noise protocol (relative to TLS)

* JMAP (compared to good old IMAP)

* Nim/Zig/etc.

* Wayland (fait accompli now, but still)

* Varlink

* Fish shell

* YAML/TOML

* Sq?

* Meson

I wish we, as an industry, invested more in improving existing technologies instead of continually abandoning and replacing working solutions.

While I agree with your general idea my lists are quite different.

I would move Zig (innovates a lot in language and compiler design) and JMAP (IMAP is horrible and needs to be replaced) up and CMake and Bazel down (I count them the same as Meson). I would say the jury is still out on Google's tweak and on seL4.
