With the technology scaling and process improvement, do you think that existing cmos will be able to exist in future?

Regardless of improvements, CMOS technology is very likely to dominate the semiconductor industry and will continue to evolve in the near future. Even in the present day of advanced CMOS, older TTL, RTL, and RTL designs are still able to find their markets. We can however, nevertheless, conclude that a newer and better approach will displace majority of current semiconductors. 

omg taking this same test i was stuck on the same question i was too lazy to read the book sadly i cant really give you an answer to this question too complex the answer will be in chapter 5 of the cay
