Type conversions, even non lossy ones, can teach people to use the wrong type, in c++ it's very common to see people use a int in a for loop indexing an array when you should always use size_t for that purpose. This misuse is so widespread that people hardly even know that the size_t type exists. https://www.viva64.com/en/a/0050/ https://www.viva64.com/en/a/0050/ has some nice material about why this matters and the type of bugs this can cause.
