What’s the Best Modern Computer for Encouraging Creativity in Kids?

I'm searching for a modern computer that replicates the experience I had growing up with a Macintosh. Back then, I spent hours using applications like KidPix and the Amazing Writing Machine, enhancing my creativity, typing, and writing skills without the distraction of the internet. I'm really concerned about today's devices, like iPads, which often bombard kids with overstimulating content that hinders creativity and basic computer skills. Do computers still exist that are simple, blank slates with no internet access, allowing kids to create freely? Maybe I'm just clinging to nostalgia for the 90s, but I want to foster an enriching environment for learning. Additionally, I have a strong technical background in cybersecurity and automation, so managing internet access won't be an issue. My main focus is on the psychological development of children in this tech-filled world; I've noticed a decline in computer literacy among younger generations. Any recommendations?
