The IDE is where the super powers are. Like any IDE it just takes a little time. https://pharo.org/ has an online course to get into it. Being in a live system is unlike anything else - the first time a debugger appears and you fix the bug in the debugger and just hit the “continue running” button is a rush. TDD inside the debugger is amazing. And do much more. You really need to experience it, else it just sounds like hot reloading features of current tech.
