OT comment: Call me a tinfoil conspiracy theorist if you will, but I think the way games have been absurdly and unnecessarily exploding in size - typically due to uncompressed video at 4k+ resolutions and uncompressed audio in dozens of languages including dead tongues such as aramaic and visigode - is an industry ploy to push people into streaming services like Stadia.Games are ballooning in size, I have 2TB SSDs in 2 machines used for boot and games storage and that free space is dwindling faster than anticipated. In 7 years 20TB is not out of the question for regular use, especially if SSDs really do come down in price as drastically as some people hope.
Of course if (affordable) internet speeds and cloud storage expand faster, then all this local storage may cease to become an issue.
And on your final phrase well, the wet dream of current Silicon Valley is moving everything to the cloud (including the OS we're running and even the BIOS/firmware of our devices), and local storage for consumer equipment ceasing to exist. Basically a regression to using dumb terminals connected to mainframes, except this time it'll be fully under their control.
