When you speak with IT Professional about the glass being half-full or half-empty, she/he will tell you the good news that the glass capacity will increase by 100% next year and the cost of that "half-full or half-empty glass" will be reduced by 50% - as predicted by "Philmore Glass Law"' written by Dr. Philmore Glass, 100 years ago, about filling more in the glass year after year. Just a word of caution: She/he may not give you the heads-up that it will cost you 50% more next year, and year after year - to get your question answered by her/him, or to get tech support from call centers located in foreign countries.
