That's a conversion, not the same. The naive equivalent to transmute would be
int8_t x = 2;
bool y = *reinterpret_cast<bool *>(&x);

My point is, in your exact example both reinterpret_cast and C-style casts have the exact same behavior, making the example bad. If you want to showcase a deficiency of C++, it would make sense to pick something where the difference between cast types actually matters.

std::bit_cast is
const bool z = (const bool)((int8_t)2);
Is perfectly valid C++.
