Can't help but think biotech at a level we can hardly even imagine, will be our not so distant reality... Super micro machines to fix what ails us or repairs us at the nano level. No more shotgun style prescriptions/therapies; rather precisely tailored treatments/drugs based on your unique chemistry/DNA and diagnosis. Truly amazing robotic surgery, far better, less invasive testing and diagnostics, incredible prosthetic devices/new eyes just like OE/hearing... Awe inspiring treatments and managements for pain, brain trauma, paralysis, cancer.
Also think carbon nano tube tech will be blockbuster, and applied in countless ways. Exponential growth, fueled and funded by Google, Apple, Intel, and many others yet to be discovered, will be the vanguard of this next quantum shift. Just the same, old school tech (read infrastructure) will have to be dealt with... Kinda hard to conger up H2O in a desert, I'm sure Canada would love to pipe water into the Golden state, along with all of us having a better grid, bridges, roadways... Also as mentioned, we are PATHETIC with regard to the internet; paying $45/mo for 15 meg download, dealing with a monopoly? Christ, can you even get speeds that slow in a lot of Europe/Scandinavia/Japan/S. Korea? My ISP's "bargain" speed is 3 megs down for I think $25/month. PATHETIC!
