People are talking about the complexity of blood and they aren’t wrong. However, there is another factor I don’t see mentioned. LIFE. We as of yet have no idea how to impart life into anything. We can take living things and multiply them. Recently we’ve figured out how to take living things and recode them to behave differently then they otherwise would. However, we still don’t know how to take a pile of chemicals and make them come alive. Blood has living cells in it, and to make living cells we need living cells.
