IT is still very lucrative. The key is as with anything which is to get in the door and gain experience. Anything related to rdbms/big data will always be a winner. The need to acquire, process, and make data actionable is only going to grow. Some of the list above will be gone in the next few years but learning to code and learning databases and technology is never a loser especially if you know how to generalize your experience and apply it to new areas in order to learn new things.
Even dealing with the relatively small gigabytes worth of data that I have to deal with, I spend a lot of time massaging data sets so that they can all be corralled and used effectively together.
I imagine that large corporations that deal with terabytes or petabytes of data have rooms filled with H-1B drones that write dozens of data converters so that a few math PhD's can work their wonders on the aggregated results.
Even big data doesn't sound like a likely career path for the number of STEM students graduating each year.
