Well, nothing lasts forever. Given enough time the hidden hand of free market will cause developer salaries to get so high that more people will study CS eventually increasing the supply and lowering salaries. However this is very slow process and I personally think shortage of engineers will continue for quite a long time (next 10 years easily). So "short lived" can mean a decade or perhaps two. We should be fine.
