Anything that isn't immediately profitable is fake work, anything that fails to work out means that it was also fake work.
Instead, we're lamenting that a company should "at least be trying" to pump more sewage into the river we all drink from.
What a sad state of affairs :)
The more robust security basis for the platform is a much stronger claim, and remains true as hardware and software change around it. E.g. we can improve the security of a platform by adding CHERI say, and that improves the security of a linux+android based system, but fuchsia would also get those wins on top of the existing more secure basis - the gap may be reduced but fuchsia stays ahead.
So the goal is to create a platform that is more profitable in the long term, so not "fake work".
It would appear that Google decided that there has not been sufficient evidence of success to warrant any further investment, but that does not mean it is "fake work".
Such a definition of "fake work" would mean that any project that you should never do or attempt anything if you do not have guaranteed success.
Note: Google's business model is ads. Android exists for the purpose of selling ads. The long term goal of fuchsia under this model would be a cost reduction in the maintenance of some android style product (whether it would still be branded android shrug). That's the business argument for fuchsia, and it would appear that google has decided that it doesn't think the end result is likely to warrant the cost of getting there. I think that's a shame, and I feel bad for my former coworkers, but I can't say "companies should be required to continue developing projects forever, even if it appears they won't succeed in their goals" because that would also be dumb :-/
In general, OS release 1.0 takes about 4 years. That's feature complete and ready for users, not necessarily production ready and stable.
And it runs on a kernel that started development on 1991. Also, Fuchsia is already running in some devices, - https://arstechnica.com/gadgets/2021/05/google-launches-its-...
Like we have a bunch of those under each tree in a park...
Instead they had 400(!) full time staff pulling in $300k+ developing something which nobody wanted and has not had any meaningful impact.
Maybe in 10 more years they will manage to replace Android…
