Recall that Fair Equality of Opportunity (FEO) requires social arrangements that bring it about that any persons with the same native talent and the same ambition will have roughly equivalent competitive prospects. Suppose there is enhanced technological capacity to alter people's genetic makeup, and hence their native talents, now or in the future. This change might be thought to put pressure on the advocate of FEO to revise her principle to require equalization of native talents so that all individuals with the same ambition will enjoy roughly equivalent prospects for competitive success (and why not consider the proclivity to be ambitious a trait like another that might be altered by social engineering in the service of a strong equal opportunity principle?). The issue here turns on what the fundamental underlying rationale for FEO is thought to be, or should be thought to be.
