What if the developer isn't around anymore to fix it?
It means you have picked the wrong library since there isn't enough interest in it to sustain it. You should then drop it for a replacement or write your own code. I know, there is plenty of examples of good libraries that are not well funded, so they went unsecure since developers cannot dedicate time to maintain them properly, one recent example comes to mind: OpenSSL and Heartbleed bug. On one side you have all these companies buying expensive Linux distros from respectable vendors with the guarantee if something goes wrong the vendor will fix it and on the other side, the vendor pocket the money and doesn't fund the developers that make him existing in first place or at least the most critical libraries that justify the companies to buy Linux instead of getting it for free and funding directly the projects they believe they critically depend on.
Well, this is just a very thin part of what the web/internet is. Just consider all the components that interact together to make the internet possible. The level of sophistication and efficiency of routing, transmission algorithms. The management of the whole thing. The cryptography field which has litterally boomed with the internet, and so on, and so on.
It is not because someone makes an insignificant usage of the internet, the internet is insignificant. It has changed much more the lives of people than the space race in much less time. Try to imagine the world without it. It is just the beginning. This is still work-in-progress.
Exactly! It is silly to say the space shuttle is far more complex than the internet/web. The size of a project like the space shuttle is dwarf by the size of a project like the internet/web by many magnitudes of order. There is much more technology into the internet than in the space shuttle.
For the AC poster who seems to believe there is an argument about making a distinction between the web and the internet, there is none. HTTP is running on top of the protocol stack that runs the whole thing and the network is the hardware part without which the protocol has no purpose.
