In 2 years, that will be 30 years ago. If RAM doubles every 1.5 years, then in 2 years a new machine should have 16G RAM (x1,000,000). At the moment they have about 4GB, so it's not far off.
You could also buy 32KB RAM for a ZX81 - but it felt a little out of reach. It was expensive, unusual, non-standard.
The thing is, 16GB RAM will soon be ordinary. Every PC will have it. What things become possible that are unthinkable today? Maybe multiple virtualized OSes could become standard.
