We're getting good at building artificial nonorganic heart, still a bit away from growing conventional hearts. I wonder how these future options intersect, whether one will win out over another, or we will be having hybrids? Electromagnetic motors work fine, but a big issue with them is the method of powering them and maybe biocompatibility issue. Normal organic hearts don't have this disadvantage but their downside is that they are in its infancy?

One word: 3D printing. Ok that was two words, but still exciting.

  This has absolutely nothing to do with 3D printing.

    They're talking about bioprinting which is a rapidly developing field, with a lot of recent successes in "printing" liver tissue: https://3dprintingindustry.com/news/tr-biofab-pulls-off-breakthrough-3d-bioprinted-liver-tissue-transplant-192682/ https://3dprintingindustry.com/news/tr-biofab-pulls-off-brea... Being able to have a 3D printed liver is very plausible within the next decade. https://www.3dsourced.com/guides/3d-printed-liver/ https://www.3dsourced.com/guides/3d-printed-liver/

      Liver is a fairly special case in that it is a sludge in a bag, a bit like kidneys and other filter organs. The subject here is a heart. There is absolutely no way that we're going to be 3d printing a heart in the foreseeable future.

An organic heart can self-repair itself, unlike the mechanical one. It's also "proven" to potentially last 100 years with no maintenance required.

  A mechanical heart could in theory be more reliable and less susceptible to issues of biology.

    Biological tissue is several orders of magnitude superior to mechanical organs.

An example of this is the Carmet artificial heart from France. It has mechanical bits but also is made of organic tissue that is incorporated into the mechanical device.
