30 years ago, my dad and I watched a VGA demo on our IBM PS/2. We were blown away that there was enough color depth and resolution to see what was clearly a photograph, not an illustration. It appeared line by line.
Someone had taken a photo, somehow digitized it, distributed it, and we were looking at a representation good enough that we could tell what it was.
It felt like we were living in the future - me as a middle schooler and him with decades of software development under his belt.
The iPhone maps app with the GPS dot and DALL-E are the only things that have matched that feeling.
