I wonder how much revenue an average person would be able to get off of their entire set of hardware (smartphones, PCs, laptops, smart TVs etc.) if SONM pops off.
Well the more people make, the higher inflation will be. If the whole world becomes rich, no one is rich
That's true. But if everyone becomes richer, everyone will be richer nonetheless. Also, there's always going to be a very select group of outliers who push things further and further, no matter how far humanity has already gotten.
Ultimately there will always be a 1% and a 99%. Even within the top 1% there's another layer of 1% and 99%.
Heat death is pretty much the only scenario in which this pattern might break.
