I wonder if these unsung heroes in bitcoin's era are also given their proper reward for their contribution to the development of bitcoin. Way back before, I highly think that satoshi alone created bitcoin, thinking that blockchain already exists but no, Satoshi together with these people helped the whole world to have a currency that solves most of the problem and inconveniency that fiat currency is providing people for a long time. I believe, they still continue working in relation to how to better increase the efficiency of bitcoin and I hope soon, I could also contribute to its growth.
