You'd think my ideal self-interest is for no one to volunteer for any research except my own relatives so that all medicine is optimized to my care. But that doesn't work that well. The genome itself is just not that useful. If you learn something from that VCF for a whole-genome sequence that's interesting, feel free to let me know.
I personally benefited from the aggregate that is the UK Biobank's repository of genome sequences and medical histories, and I'm grateful for everyone who contributed that for science. PGP is the closest I can get to providing my data apart from All Of Us which has a bit of medical data about me but no one has all my medical history.
I hope that, if nothing else, I am a piece in an instrument for humanity to comprehend the Universe. Either through my genome being useful when compiled with others or as a cautionary tale to making your genome available.
