Change the Defaults in C++
summary
C++ defaults cause real harm: a UK Horizon bug saga leads to about 900 convictions and 236 imprisonments with reported suicides, and hospital scheduling software leaves cancer patients unable to start treatments repeatedly. Recommendations are concrete: avoid undefined behavior where possible, add runtime checks for features that cannot be defined, design APIs that are hard to misuse, make safety by default with performance opt-in, and invest in testing and maintainable code so defects are findable and fixable.
