Man, I like Bryan Johnson's vision. We definitely do need a global biological immune system. Along with the "global brain", this is the perfect metaphor for where we as a species must go.

Unfortunately, he's using a very poor set of strategies for getting us there. Biotech and biomedicine will *never* scale as fast as infotech, because we don't understand the science. We won't have good molecular simulations of gene-protein interactions, biocompatibility, and how to improve the immune system until we have vastly better computational power. We may need quantum computers. All of these companies are aspirational investments. They will seriously underperform infotech investments until we have predictive models at the molecular scale. That's just their nature. Infotech is increasingly self-improving, the more bio-inspired it gets. It can learn at the speed of electricity, seven million times faster than biological systems can think and learn.

If Bryan really wants to focus on biotech, I would recommend focusing on cheaper viral diagnostics and vaccine tech. That's the real danger for humanity at present, and has been since the 1970s bioweapons research treaties. We need better immune system adjuvants, vaccines, and instant tests. That will finally close off the possibility that millions of folks could die from bioweapons created by small fanatic groups. See my Medium posts on DRACO and Abbott's ID NOW as examples of tech we sorely need to scale up.

If you are going to use the global immunity language, I'd focus on eliminating the greatest threats first. My posts describe the kinds of global immune capabilities that really are highest priority, at present, IMO.

Thanks for using this global immunity language. I think you're absolutely thinking in the right space, just using, unfortunately, lower-value strategies. Good luck, but I wouldn't expect much. AI, by contrast, will continue to accelerate in coming years. Taming that, and focusing it on immunity and ethics and empathy building, are the real biggest opportunities and challenges of the 21st century.
