At the annual Denver Startup Week I notice about a third to half of the startup industry is incestuous, that provides facilities for developers to work better. These are mainly code academies and coworking spaces. I feel if the tech industry ever ever has one of its periodic down turns, then this it could rapidly implode with all these developer services.
The reality is about half of the workers entered the tech industry since its last major down turn during 2000 - 2003 and live in the fairy tail land that it could not happen to us. Welcome to economic reality, suckers.
Don't count on that. If an economic downturn happens, it's entirely possible that the less experienced, but less expensive developers will do well. It may be the experienced one will feel the hurt.
In recent downturns people without college degrees got burned. HR could ask for more credentials, even if they were less relevant than experience.
Its just its been so long since the last IT downturn, the newbies feel invincible.
