Re: Greatness
>Linus most certainly is no billionaire.
He's a double digit millionaire and I'm sure he would happily be a billionaire at any cost to everyone else, if he could.
>initiated and managed projects that ended up in improving the lives of many people
False - many of the projects he initiated and managed are proprietary software, or only came after he did his best to make the lives of many people worse.
It is common to claim that he initiated an OS - but he didn't - he saw that GNU was almost ready and only needed a kernel, and so he wrote another kernel for GNU - which he released as proprietary software in 1991.
Later in 1992, I figure he wasn't seeming much success (as GNU wasn't interested in encouraging a new proprietary kernel by supporting it), and so he decide to relicense Linux to GPLv2-ambigious and GNU out of goodwill ported every last package to work with Linux, which resulted in a much more usable kernel (as you had an OS to properly go with it), but of course the whole thing was called "Linux", which happened to attract thousands of developers to work on Linux (kernels are fun and exciting, while the rest of the OS isn't as exciting).
Later, Linus proceeded to betray that goodwill by using his management skills to allow Linux to become proprietary software again via the inclusion of the first proprietary program (of many) in 1996.
There was even a policy years ago to migrate all the proprietary software in Linux into a separate git repository (that can't be anything but part of Linux), but that's still not done.
He betrayed the goodwill again by deciding that the the license would be GPLv2-only in 2000 and proceeding to only ever enforce the license against freedom.
As for git, Linus first made as many developers lives worse as possible, by encouraging and supporting the BitKeeper proprietary software and SaaSS for kernel development (rather than using existing free software version management or if that wasn't suitable, writing functionally better software), as the deal was that gratis access would be provided in exchange for the advertising.
Later every single developer that fell for it was burned, when their access was terminated (and only then did Linus decide to clean the mess up with git, which is convenient, but hard to use and I don't see how convenience alone particularly improves lives).
Of course he later betrayed everyone again, by encouraging the usage of github (his only complaint was that the commit metadata is not complete), but his words don't meet his actions, as he did accept a commit on github.
- As for Sparse, well that's a static analysis program for Linux that is convenient (as less bugs), but that doesn't seem to improve lives.
- As for subsurface, well that's a convenient program, but it's only useful for divers (which aren't that many people).
I really can't find much else he's done, other than his fork of a proprietary version of emacs.
>Linux already affects, and improves, the life of nearly all humans by way of Android
Android in fact is a net negative on the lives of almost all humans - it spies on them, restricts them and is proprietary software for almost all of its users,
As it became possible to do so, constant attempts have been made to force people to carry around a surveillance device, so they can be made available 24/7, which is total insanity and clearly does not improve the lives of anyone (but notifications every 5 minutes must be a good thing).
There is no technical reason why an Android phone that can make calls and the like, while not spying on you, but not a single model has been made that doesn't do that.
I am confident that the world would be a slightly better place without Android (too bad other proprietary mobile OS's would likely have become popular instead).
Regardless, google is currently working on a replacement to Linux for an OS similar to Android; https://en.wikipedia.org/wiki/Fuchsia_(operating_system)?useskin=monobook so the software that goes on future mobile devices can be 100% proprietary, instead of 99% proprietary - but it's not functionally good enough for general usage yet.
>the network and cloud servers that run all communication and social networks.
Social media has been a net negative on humanity in all cases - such companies have done numerous studies that concluded such and of course such companies did not stop, but CEO's and the like do ensure to not allow their children to have an account for a reason.
Current communication networks are a net negative on humanity due to all the spying, spamming and monopoly costs that are imposed on the invocation of proprietary SIP and RTP protocols required to communicate over such networks.
Linux alone is useless for networking - the networking stack needs to be configured what to do before it does anything and you need other daemons to handle protocols like BGP and even SLAAC and well you need GNU to setup the routing rules and run the daemons.
Other kernels and OS's do implement networking protocols as well, which are used, although less commonly, as those aren't as convenient.
There is no cloud - those are all someone else's computers - it doesn't make much difference what OS a server runs if it's used to spy on you.
