Why are we comparing coding bootcamps and CS undergraduate enrollment? There is very little overlap here. Apples and Oranges.
Seriously people, if you didn't get a CS or CompE degree take it from someone who has: you don't really learn to program in college. You don't. Most engineering disciplines take a CS101 intro to programming where you may learn the basics of Java, you might make some really basic programs where no one will teach you style, design, code reusability, architecture, anything. If you click run in netbeans and some numbers spit out in your output window you get a passing grade. Thats it. For the rest of your college career you are on your own. Most people graduating with CS or CompE degrees can't program professionally, but they have the tools to learn from others and teach themselves. From my experience in about 3 months with someone willing to be a sort of mentor/teacher they can stand on their own professionally.
So now that we understand that you don't learn "coding" in a CS or CompE curriculum, I am again asking: why are we comparing CS and boot camp enrollment? The headline insinuates that they are similar when they are very very different.
Now a message to practitioners (this may only apply in the embedded world, nomenclature varies drastically between embedded, desktop, web development):
Software Engineers: people coming out of bootcamps aren't going to take your job! You have to know this.
Programmers/Coders/Keyboard-Fu artists: well these people are going to compete with you for your job but I'm guessing you don't have a CS or CompE degree, and if you do explain to your boss that you can do software engineering and you're not just a human input machine turning someone's designs into code. If you are you never had a lot of job security anyways. (I personally don't believe in the "Engineer makes the architecture, coder implements the design" pattern, I and many much smarter and more experienced people insist that the designer/architect must code).
There is a lot of negativity around here directed towards the boot camps. I was sceptical too at first, but the more I thought about it the more I feel like these boot camps are very similar to community colleges. Unfortunately there are companies who insist that software engineers should make UML diagrams all day and then hand everything off to some poor sap that has to decipher incoherent nonsense and make a functioning piece of software. Thats where these bootcamp people fit in.
There are small businesses that need someone to write a basic shopping cart module for their website. Perfect for a boot camp graduate.
There are professionals and business owners who really want to learn how to do basic coding but don't know how to teach themselves, they are perfect candidates for boot camps.
If you think you are going to have a 35 year career with just a boot camp certificate alone you may want to rethink that strategy. Otherwise these things aren't bad.
