Making a second comment to answer your actual question:
For me it’s when technology is very uniformly high tech. So for example in the real world technology advances but it doesn’t advance everywhere at the same speed. There might be high tech versions of things in cities while you still find old or ancient equivalents out in the countryside (or just both types existing alongside each other all over). I really like it when SciFi can capture this nonlinear pace of technological advancement.
Yes! Great example of it done right.
