Here's an estimate of ARM's revenue per chip at 10 cents (profit maybe half that).

Here's an estimate of youtube (not exactly tiktok, but not exactly not), revenue at 10 to 30 cents per view.

Sorry, this is wrong by an order of magnitude. Youtube is making more like 1-3 cents per view.

that article makes me wonder if the beos would have survived if they switched from Hobbit to arm chips and stuck with selling hardware+software, and later on added x86/x64/PPC/POWER. A tight integration of hw+sw has worked for apple.

My guess is no.

I loved BeOS, but there was an even more fundamental problem that put a limit on its days: A failure to anticipate coming need for home computers to become more secure. At the same time that Microsoft and Apple were both working frantically to ditch their old single-user desktop operating systems and replace them with, in effect, spruced up versions of existing server/workstation operating systems, Be was trying to launch a brand new OS on the dying model. Had they survived even a couple years longer, they would have had to reckon with that, and they simply didn't have the resources to navigate such a fundamental transition.
