It's a nice article that sort of positively boosts interest in the industry, but quite honestly, unless you've got an awful existing job, a spectacularly unique idea and personally know the right people who can help you pull it off in advance, the video game industry is often horrible to work for. Very long hours, high "salaried" competition vs outsourcing / freelancing, unreliable income from smaller publishers and horrible working conditions / expectations / high levels of stress from the larger ones. Best way in is hobbyist, ie, you work for free in your spare time and hope that whatever simple game you make takes off.
Most salaries quoted in "industry advocacy articles" are generally inflated by quite a bit. Eg, most "audio professionals" certainly don't "average" anywhere near $96k (avg salary for an audio engineer is more like $44k with only a very few near triple digits). The Gamasutra figures on which the quoted $96k figures were based asked only 33 people (all salaried), freelancers (your real competition starting out) were not counted, and as other sites found the real industry figures are lower:-
"Employed game audio professionals make an average of $70,500 per year, have been in the industry about 8 years and worked on an average of 3.8 games in the past year."

^ So that's an average of $70k for people with 8 years of experience with multiple games under their belts = you quitting your job and just starting out fresh-faced will be more like $20-40k.
You also can't "train" for creativity. No amount of musical degrees or training or reading positive thinking articles will magically turn you into a Jeremy Soule or Inon Zur just because you fancy a change in career. Composing is an innate talent that you either already know you have by the age of 18 (eg, having spent childhood attaining 9th grade on piano with a deep passion for music), or you don't.
Don't want to sound pessimistic, but there are many "lower stress" career changes I'd consider first (including lion tamer, wing walker and bomb disposal) than video game development, especially if your existing career has zero overlapping experience with whatever you're aiming for, and you have a family to feed...
