Over the last 30 years , computing costs have dropped by a factor of 10 each decade and capacity has increased by factor of at least 100 each decade . Today's microprocessors can put a mainframe on a desktop , and eventually into a briefcase of shirt pocket .
The future will see even more intelligence built into...
