Not to mention the socio-economic impact of who is chosen and who isn't. The movie Elysium comes to mind. That said, I think research on samples and growing tubes is fine. I hope for the day when we can just grow a new heart or lungs or pancreas for people who have cancer or something. Taken from their own "good" cells so there's no rejection.

Yawn. The most boring and lazy complaint to this technology that I can imagine.

If we can edit, then in time there is no reason why the technology will not become affordable for the vast majority of the population.

Like insulin?

I think you might still run into rejection with that since its like not in sync with their immune system. So it would probably be better to temporarily have them on a pacemaker or mechanical heart while you grow a heart inside of them to replace the old one. Or the equivalent for other organs.

What does it mean to be "in sync" with an immune system?

AFAIK the immune systems works through antigen detection, the antigens that your immune system recognise as your own are innate to your own cells and are expressed automatically
