And I owe it all to Windows Vista!
Let's upset some applecarts, yeah? What do we need that we don't yet have?
* Tricorder - tomographic spectrometer + noninvasive blood analyser
* Weakly godlike software - for now better sorting algorithms, something that can separate spectographic patterns
* Good cheap optics (rep-rap)
* Automatic cheap astronomy (seems unrelated but really isn't)
* Metal reprap, Replicating Mill (lost wax method?)
* Cheap CCD chips (no idea how to pull that off, but with luck someone else will do it)
* no seriously - lost wax method. carve the darn thing and cast
* autodoc - dispenser of organics, think... the BarMonkey of Harvey Mudd.

Towers of powers, remember? in the 1960's we put these algorithms away for good because their computational complexity was a joke. they wrote a seed, a seed that could never unspool into what it was intended to be because the systems of the day couldn't handle it.

Four decades of Moore's Law later, we've built systems that can handle /Vista/... it is time to dust off some history books.
