We programmers and data scientists might find ourselves among the first half of knowledge workers to be replaced and not among the last as we previously thought.
You can write code that is valid as in "can be compiled" but outside of C++ standard. It is duty of programmer to not have those, as compiler usually assumes that there's no UB in your code and can do unintuitive things with optimizations.
e.g
int foo(int8_t x) {
x += 120
return x;
}
int bar(int8_t y) {
int z = foo(y);
if (y > 8) {
do_important_thing(z);
}
}
1. signed overflow is a UB. Compiler than assumes that everything passed to foo is less than 8;
2. We pass y to foo => y < 8
3. if branch can then be optimized out
I was too lazy to check the exact value of 2^31 and payed for it.
Instead of semantically correct Python, programmer and data scientists’ jobs will be to work in semantically correct English. Fundamentally the job won’t change (you’ll be programming the AI rather than program the machine directly).
