people who thought "getting into computers" meant easy money
just like all those who got their Web Developer certs and flooded Silicon Valley over a decade ago. Sock puppet dot-coms and other stories of Money for Nothin' (Dire Straits in your head now?) drove up interest till the Dot Com Bomb.
Recently big hype in "Coding" as some sort of panacea, where kids were lead to believe easy shifts in air conditioned offices, working with beanbag chairs and Smart Executives Who Get You, free parking for your Fixies and Craft Beer brewed on site, and complimentary trimming of your hipster beard were the truth about Working With Computers.
Reality, not so much, and not for the vast majority. A life of "contract" positions, promises unfulfilled, and the same "stupid bosses" as every other field, along with finding that coding is pretty much an antisocial game at worst, and at best, just another job, lessens interest.
the oft predicted glut of "coders" also turned it into a "buyers' market" where even those high profile positions became less valuable as fresh "geniuses" could be hired for a lot less, made it even less desirable to "the youth". Not to mention many kids have parents in that field and have seen the reality.
Add in the ability for "work from home" to become "replaced by overseas contractor" and the competition for primo coding slots becoming WORLD wide, those who aren't as good as their school teachers praised them of being, find themselves overlooked. When Google or Apple put up a position, the very Best of the Best of the world apply. And only so many "studies" and complaints about "racism" or "sexism" can get someone hired when their A game simply is not world-class. Its like the Olympics, the Superbowl, the NBA Championships around here.
And like big sports, no matter how many thousands of students you run thru Podunk or Big City High's basketball team, and all the trophies you got "getting to State", there's one Steph Curry. (or KD). Even your LeBron's end up not getting the plum jobs here all the time.
And that's before we even examine issues of "aptitude" or "desire" when discussing education based emphasis on a single career type.
