For inkscape, some of the more sophisticated generative things were "use and forget" for me but they have actually improved to be much more intuitive. The main thing I lose is some of the natural touch that makes it so fast to use. I do love when I use it regularly because it's so quick to pump about svgs at the speed of thought.
Getting really good at a vector tool is such a valuable life skill for explaining all manner of tricky things whether it's for UI mockups, software architecture or graphic design stuff like logos/t-shirt/marketing designs. I live for the "how on earth have you done this?" reaction when I can create a quality diagram while on a call with people. It can really enrich the quality of interactions and reduce cycle time to create designs in real time.
I also use it for all sorts of personal stuff like interior design, DIY, scaffolding etc. I've even submitted official architectural plans I made with it. It's as valuable as a spreadsheet.
