Why has CPU progress slowed to a crawl?

Why can't we go faster than 5ghz? Why is there no compiler that can automatically allocate workload on as many cores as possible? I heard about grapheme being the replacement for silicone 10 years ago, where is it?

I think you have a misconception. the clockspeed of the processor is not an important metric of performance. it merely represents how much power you're running through the circuit. it is only indirectly connected to real measurements of performance. 

a real measurement of CPU performance is Instructions per Second. that measures the rate that a CPU can execute programs, which is a direct measure of how much processing capacity a chip has. 

there are many strategies to increase Instructions per Second and increasing clockspeed is one of the worst of them. more recently CPU research has focused on increasing parallelism (by adding more cores to each CPU) and increasing efficiency of data reading and writing by increasing the amount of high speed cache memory available to the CPU. both of those strategies dramatically increase Instructions per second but don't require any increase in the clockspeed of the processor. 

there are also many good reasons NOT to increase the clockspeed. running more power through the chip causes serious overheating problems. the more power pumped into a circuit the hotter it gets, due to the resistance in the circuit. heat can cause serious damage to circuits and is probably the single most prevalent cause of failure (mostly due to melting or mechanical failures from overheating). increasing the heat of a chip also increases the need to add cooling systems as well, so this ends up being an expensive and inefficient strategy for increasing performance.
