From the perspective of someone who's been writing Rust professionally for the last few years, the hockey-stick curve started kicking in in late 2020 or so.
But you can even have a rough estimate according to your own measure. There are roughly between 50K and 100K developers working at FAANG (maybe replace Netflix with Microsoft). How many of them would you guess are using Rust?
Why would you want Rust to target lowest-common-denominator developers and become new VB or php? All it needs is enough momentum to become self-sufficient, which seems to be actually happening now with Rust Foundation and news of its usage in some major companies that can set the trends for whole industry (Amazon, Google, etc.).
Rust wants not that I wants. It seems people replacing NodeJS with it.
