No, a 10x increase in the network hash rate from today's rate, results in roughly a 2 year payback for K16s if BTC stays stable around $100.

Based on network growth during the FPGA/GPU era, the hash rate growth quickly slowed and then stopped when the payback reached around 1 year.

This is logical, when it takes over 1-2 years of mining just to break even and there are risks that some new technology will disrupt that, why not just buy BTC? Maybe now with professional mining companies a slightly longer payback will be accepted, but I don't think we're ever going to see network growth when payback exceeds 10 years anytime soon.
