It’s kind of frustrating because people who don’t understand programming or how the internet works are using algorithm to refer exclusively to the ones used by big tech, with machine learning based on user choices and whatever data they feed it to trick users into staying engaged longer.
Though algorithms are any program or sorting routine, however most people don’t understand this and they just think (even if they’re not willing to tell you) that algorithm just means magic or something like that because they’re imagining the machine learning ones they don’t understand that the simple algorithms like sorting by new or most popular are still algorithms.
