This question shouldn't be being downvoted as much as it is- it is a legitimate question although would probably go better in its own set in the open thread rather than a discussion section.

Yes, this has been discussed a fair bit- the main argument in most transhumanist circles when this comes up is that everyone will get the benefits and that birth rates will go down accordingly (possibly by enforcement). In that regard, there's a fair bit of data that humans birth rates go down naturally as lifespan goes up. There are other responses but this is the most common. It is important to realize that it is unlikely that this issue will need to be seriously addressed for a long way off.

The volume of comments generated indicates to me that it is too large for an open thread.

Stinky motivated stopping. Birth rates aren't the only problem. Personal growth causes the same problem.

Agree about not actually needing to address this yet. our future selves will be much smarter and still have plenty of time.

Speed of light latency puts limits on the maximum size of a brain. Or, rather, it enforces a relationship between the speed of operation of a brain and its size. At a certain point, making a sphere of computronium bigger no longer makes it more effective, since it needs to talk to working components that are physically distant. Granted, it's not a small limit, especially if people want a bunch of copies of themselves.

Good point. Should I move it? If so, I don't know how.

I'd really like to see anyone here who really knows what they're talking about (I don't, for example, but I want to know) discuss it here. Currently looking for both a plausible situation and solution.
