It's good people work hard for the right livelihood! Having studied and trained in computer studies and programming, I know how fast and much this industry can and have changed. For a good and steady lifestyle, I hope people have a consistent, good-paying harmless work, without having to worry about making enough or when will be the next payout. Alas, this is not a work or industry that I wish anyone to take upon as a career or even hobby because of its fast-changing needs and development. While I'm glad people learn logic and systematic way of thinking, but there may be way too much change and dynamism to the point of restlessness - NOT likely something you want or can DO five, ten, twenty months/years down or in your retirement. One may not feel tired right now, but he should or will be. Who is getting younger and should/can one compete with more and more quick-minded and talented teens? And progression of development in future may only get faster, more complex and harder.
