Could C++ handle an ABI break? The 2026 case
Two pieces dropped in the same week: Luis Caro Campos' CppCon 2025 talk arguing package managers make ABI breaks manageable, and an HFT University article claiming a 58x P99 latency gap between Rust's and C++'s stdlib. The ABI debate is back. Here is what both sides are saying, and what C++26 shipped despite the constraint.
