There is a broader picture to these lessons that I would like to point out: Not only is it economical to do bad work if you bill by the hour; but it is also necessary to build flawed products to sell more of them. See printer inc, light bulbs, computers, everything that could last 100 years but doesn't... The other side of this is that energy is considered free, if we paid the real price for oil/electricity it would cost many thousands dollars per gallon/kwh. The only way for this to change is for the whole system to collapse, and that will happen during this decade. All arbitrary (not based on experience from nature) human skills are going away. But math, physics, chemistry and biology will stay; prioritize in that order. Build a good computer today, it will not become obsolete technically for the rest of your life. Buy a ARM computer that you use as desktop, it will be usable for the rest of your life AND it will teach you to become a better programmer!
