I like that! Quite a curve! Now a terabit thumb drive. A gig of internet speed to your home. Wireless communication between all of us at video speed, anywhere. Huge 4k TV screens for less than $1000.
Now we learn that our data centers are gobbling power. Add to that the gobbling by the billions of electronic gadgets owned by all of us.
