For a naive adder, sure. Actual adder circuits use carry lookahead. The basic idea is to “parallelize” carry computation as much as possible. As with anything else, there is a cost: area and power. Edit: This wiki page has a good explanation of the concept: https://en.wikipedia.org/wiki/Carry-lookahead_adder https://en.wikipedia.org/wiki/Carry-lookahead_adder
