These slides discuss the potential for an acceleration in the rate of growth for bio-electronic ICs. Just as ICs benefited from reductions in scale and increases in the number of transistors per chip, some types of bio-electronic ICs also benefit from such reductions in scale and thus are likely to experience rapid growth as certain problems are solved. the improvements in bio-electronic ICs are enabling new forms of point diagnostic systems, food sensors, drug delivery, exoskeletons, and other health care related systems

    • 32. Can Equipment Provide Better Advice than Doctors?  A conversation with Vinod Khosla, co-founder of Sun Microsystems and member of Kleiner Perkins Caufiled and Byers (biggest VC firm)  Researchers gave the same info to 40 cardiologists and asked the same question  Should this person have cardiac surgery or not?  Half said yes and half said no  Whether you get surgery depends on which doctor you happen to pick? That is pretty bad. And that’s not the worst part. Two years later they took the same data to the same cardiologists, and 40 percent changed their mind. I could give you ten examples like that.
