There's different visa's for gifted people to come into the US. The H1B is not intended for this purpose you claim. The brightest won't be affected by this.
If you are in early career (i.e. graduated your PhD within the last 5 years) you are extremely unlikely to get the gifted people visa. The standard approach is to just get the H1B (not the lottery stuff for tech companies but the non-lottery one for hiring faculty at universities). Ask any foreign MIT professor hired early in his career and they went through H1B (and later on, they are more reluctant to move into a place like Florida..)
