I just don't see how you can look at where we started and where we are and not be amazed how much progress has been made in 15 years. It's also unfair because a lot of the 15 years was spent actually building the technology to make the network usable. I'm absolutely shocked at how much better things are now vs when I bought into the Bitcoin philosophy four years ago.
All of this without a centralized authority guiding development is truly amazing. We are farther ahead than I expected. By years.
