I’m amazed/skeptical that science could add something to millions of years of evolution and make it more efficient.
Bone works great until it fails catastrophically (ie it fractures, breaks, and shatters) while titanium will begin bending long before it breaks. The latter is generally preferred in engineering structures, but since a human can heal its bones, the sudden failure is an acceptable compromise for consistent performance even at high loads.
Finally, bone weakens as we age, as does the body's ability to heal itself. Eventually wear and tear will make joints highly uncomfortable and the potential damage from otherwise minor injuries significantly greater. Titanium holds up well in the body over human timespans, and our ability to replace titanium components far exceeds our ability to artificially regenerate bone.
There are good reasons why evolution favored a composite like bone for our structural elements, but if you could magically replace your skeleton with one made of titanium once you were past your prime, it would be an unambiguous upgrade.
Take an anatomy class, and you'll be amazed at how poorly configured human knees, lower back, appendix, vagus nerve, etc. are.
Like, just look at laryngeal nerve. It's pretty dumb that the nerve has to go around the collarbone. But it's not surprising when you think about the iterative nature of evolution. https://rationalwiki.org/wiki/Laryngeal_nerve
And let's not even talk about the size of human skulls and maternal death in child birth.
Microprocessors, for example, are not a result of creation science.
Civilizations that invented computers and electronics used to be more successful than other civilizations at reproducing and everything else. Used to.
