It's not a literal point, it's an observation of how far we've come. A single texture blows away 2600 and NES games in size quite handily. The emulation effort for either is a sneeze compared to what we pour into a single frame nowadays. Compared to modern stuff they're both just primitive beyond primitive as far as a modern kid is concerned.

And as for your second paragraph, it has that thing I don't understand that so many people seem to have in their brains that if you explain why a thing is true, it is no longer true. I do not understand it. Explaining why they haven't moved on does not suddenly make it so they have moved on. They haven't moved on. Best of luck to them but I doubt it's going to work very well as a strategy in 2025 any more than it did in the 1980s.
