The fastest JVM is the C++26 compiler
Koen Samyn's BeCPP talk used std::meta::substitute to transform Java bytecode into executable C++ at compile time. The compiler constant-folds the entire program. The loop doesn't run faster. It doesn't exist. This is reflection used not for serialization or enum-to-string, but as a compile-time metaprogramming substrate for building language interpreters.
Sutter's BeCPP keynote: C++ added more developers in 4 years than any other language
Herb Sutter's keynote at the BeCPP Symposium 2026 (March 30, Howest, Belgium) opened with a SlashData chart almost nobody outside the room has seen yet: C++ developer population grew 72% from Q1 2022 to Q1 2025 -- from 9.5M to 16.3M. That is the biggest absolute net gain of any general-purpose language over the period. Rust grew faster in percentage (137%) but on a smaller base (5.1M total). Here is the chart, the numbers behind it, and the thesis Sutter built on top -- plus an honest read on what 'fastest growing' means when JavaScript is still bigger than the second + third place combined.
