I think the point here isn't about how quickly videogames or consoles boot, but rather that if your program takes longer to start than a significantly more complicated videogame from the same era, then you're doing it wrong, and as a result wasting your users' time.
It's a view I shared in the past - it held throughout the entire "desktop computing era", until consoles and PCs started to converge, and the asset bundle size of a typical game inflated rapidly.
