a$.)$ Finance and budgeting $-$ how often will companies need to replace their systems$($ie$.$ CPU's$)$ in order to maintain equal processing capacity if their business workloads are increasing $100\%$ each year? Will standard $4$ year refresh cycles for PC$\text{'}$s get longer or shorter? Show your math and logic.

b$.)$ Systems Development$/$SW Engineering $-$ Does it really matter if the programs are written efficiently, if the speed of the CPU will $2$X every year?

c$.)$ Facilities & Space requirements $-$ Why are the size of the computers $($or phones$)$ not decreasing proportional to the decreasing density of the CPU's? Same question for size of data centers housing the servers with CPU's that each year become "smaller, faster, cheaper?"

d$.)$ Types of applications now available $-$ Give some examples of new application categories that have arrived in past $10$ years as a result of Moore's Law.
