I’m not sure why we need to be sarcastic about a future in which “we upgrade ourselves into transhuman”. There is nothing special about “humanity”. Emotions are likely result of chemicals. We will transform ourselves and what those beings feel most likely will not resemble what we feel today. They will have their culture and art and they will not care about ours at all. It is inevitable if there is no disastrous event happening. We just need to accept that. We are one tiny step in evolution like dinosaur.
