Moore's law - 50 CPU cores by 2021?

From https://en.wikipedia.org/wiki/Xeon we have the following data:

Year	Process nm	Cores
2001	180	1
2002	130	1
2004	90	1
2005	90	2
2006	65	2
2007	45	4
2010	45	8
2011	32	10
2013	22	12
2014	22	18
2015	14	22
2017	14	28

Intel Xeon currently has 28 CPU cores and if trend continues then by 2021 we should have 50 CPU cores. With commodity two CPU server in 1RU we can potentially have 100 CPU cores. With virtualisation a 3:1 vCPU:pCPU ratio can have 300 vCPUs on such a server...assuming average VM is 2 CPUs then 150 VMs on 1RU. MIT Technology Review suggests that after 2021 it will it will not be economically efficient to reduce the size of silicon transistors any further. The 5 nm node was once assumed by some experts to be the end of Moore's law. So lets enjoy it while it lasts! 😊

Now a 2 CPU server can have 112 CPU cores and 3TB of memory, assuming average VM is 2 vCPUs then type of server can potentially support 150-200 VMs:
