This is my favourite take so far from this post:

"Google’s own data from September 2024 shows that Android’s memory safety vulnerabilities dropped from 76% to 24% over just six years — not by retrofitting safety features onto existing C++ code, but by writing new code in memory-safe languages (Rust, Kotlin, Java). Google’s security blog makes a fascinating observation: vulnerabilities have a half-life. Code that’s five years old has 3.4x to 7.4x lower vulnerability density than new code, because bugs get found and fixed over time. The implication is striking — if you just stop writing new unsafe code, the overall vulnerability rate drops exponentially without touching a single line of existing C++."

Starting to transition away is perhaps the best step if these stats ring true. Then actively seeking out bad C++ practices is probably going to quietly pay dividends as well.
