I wouldnt be surprised if 1 full node can do 200 tps with 2 cores if software is slighly optimized.
Your extrapolation is wrong, CPU load from DAG traversal/analysis ~ TPS
3/2 - TPS
2.

IOTA is perfectly designed for the M2M industry, internet of everything, but not only for this!
Will you correct the user, and tell him, "Correction, IOTA does not work on internet of everything any better than any other technology despite being designed for it"?
