Easiest way to do this stuff is before fertilization when you have one egg and one sperm to work with. Delivering change through a multicellular organism is very challenging. All this stuff like transgenic mice are set up in mutant crosses before this stage, before mating really.
Eventually this will be the outcome of our species to edit the gametes themselves. The issue to overcome for this again won’t be technological as that is pretty much solved but getting people over their own “ick” factor.

Probably requires getting investors over their profit incentive first, why treat a heritable disease for the offspring if you can charge them on a per person basis?
>>>Easiest way to do this stuff is before fertilization when you have one egg and one sperm to work with. Yes. But it seems, that nature so far is still better than we at picking better quality cells in laboratory environment. Not all eggs and sperms are equal - the difference in DNA quality varies.

The issue to overcome for this again won’t be technological as that is pretty much solved but getting people over their own “ick” factor. This is a new fear unlocked, as this will be like another cosmetic surgery procedure, which from my minimal understanding does not affect DNA that is delivered to offsprings - that could be changed but require a lot more work, but like you mentioned - it is easier to do before fertilization :). It is catch22 situation rn.
