Cancer progress in the last 40 years hasn’t been that great (I’m not discounting the hard work and incredible breakthroughs there have been, etc). I’d predict we’re closer to a cancer cure and other not so soon medical advances than a fully functional artificial womb. (10-15 years would be F-ing amazing but I wouldn’t be surprised if it was 100-150 years and aging was cured first).

Edit: bc I forgot, we can't even replicate human breast milk fully well!
