Legos are great. My son was lego fanatic and he did learn some programming on mindstorm (rcx) and did some c like programming on it as well (not quite c it was called). He also learned basic from books and old tandy computers. I taught (volunteer) arduino, rpi and occasionally scratch classes at my local library pre-covid and I would say lots of kids can program at 8, and quite a few a bit younger but even with scratch being able to use a keyboard and mouse as opposed to touch screen is really important. An of course being able to read/write. I think just having fun computer things around the house that are not video games is good. Scratch is actually pretty awesome I think for learning programming, and then stuff that actually moves is really cool. I was also lucky in that my father in law actually had a robot company (ibm pc, basic programming, lots of cables) and he sent us one to play with when he as maybe 8 or 9? But there are so many choices today. Good Luck!
