Your post is completely detached from the reality of the computing world.
CDs are used all the time, for a variety of reasons. For example, we have to use imaging discs because our, get this, Windows 8/8.1 machines will sometimes not boot from the imaging server.
Heck, I don't think you know anything about computers. We have bought close to 100 machines this year alone (3 different models), all with a CD drive.
Seriously, go spout your nonsense someplace else. You clearly have no idea what you're talking about.
Are you kidding me? First of all, learn to read:

So not only are your posts completely detached from the reality of the computing world, you also don't seem to mind shouting about things you clearly don't know. Typical stuff from you.
And recovery/repair discs are not a thing of the past. They have to be used for a variety of reasons. Quit spouting off about stuff you clearly don't understand.
Nonsense, when you're working with hundreds of computers, some of them are going to fail (whether due to incompatible drivers, malware, software installation failure, etc.). There have been a couple of times just this year where I needed Safe Mode.
How freaking ridiculous is your post?
I'm thinking you should know what the hell you're talking about when it comes to computers before you try to give me advice.
