people doing the most #AI research aren’t your run-of-the-mill software engineers; they don’t care about memory management, const references, and multiple inheritance. They want tools that allow them to visualize their data, put together an experiment in just a few lines of code, and interact with / alter their data and model without needing to recompile and rerun for every minor change.
#Python lets them do all this, C++ does not.
