If you are a tech-freak of sorts (like myself) then you probably concern yourself with happenings such as the release of AMD's (or Intel's) quad core microprocessors, dual GPUs, terabyte-sized hard drives, and all other sorts of tech-geekfoolery in existence. Nonetheless, it may seem rather disconcerting to inquire about the need for all these advancements. Interestingly, an article on The Inquirer addressed part of this issue (Core Insanity Replaces Megahurtz Madness). If you don't mind me deviating or displaying my ignorance just a little bit, why on earth do these The Inquirer folks insist on using horribly mindblowing language and acronyms such as "DAAMIT" (AMD/ATI), "The Vole," and all that other nonsense - they have interesting viewpoints though! That aside, the aforementioned article addresses the sensibility in purchasing affordable hardware that one will not regret having obtained six months down the line (the point of which is obviously functionality!)
Nonetheless, these techonology advances beg the question why? Say 30 years down the road we have machines powerful enough to understand speech, perform horrendous calculations in nanoseconds (such as factoring numbers or solving discrete logarithm problems - using brute force), etc. Of what use would these be to us? Ultimately, anything we make is of any value to humanity based on its utility. What can we do with it? Entertainment's currently one flourishing arena. The Nintendo Wii, the Playstation 3, and the Xbox 360 are just a sampling of what sort of entertainment is possible with number crunching, vertex spinning, pixel churning power. How much more is needed though before we'll be satisfied and say "well, we can now stop development since we've come far enough."
Perhaps that's the beauty of the enterprising human spirit - we always find a new utility. After all, God's command was to subdue the earth (and fill it :D). Subduing and caring for the earth definitely involves discovering the workings of nature. Perhaps I should clarify that I consider mathematics to be a fundamental part of nature, a viewpoint not shared by many. In light of this
the pursuit of faster computers (robots, CPUs, GPUs,
I do admit though that I at once realized the implications of more power
Did I say I love science/technology (oh, non-MLA citation: "the PS3 image if from Wikipedia")
