Its sad to see the Monero 51% attack - while not Bitcoin their hearts were genuine in its goal. Hope they are able to resolve the situation. What it does tell you though is answer the question "why not just make another better bitcoin" What makes Bitcoin unique is not the code - its that its Bitcoin This is why people often say Bitcoin was discovered No new copy would work because you needed a decade of network effects with great skepticism with quiet but no broad understanding in order to scale past death point Now the game theory and understanding is wide that such a thing starting now would be captured early from game theory understanding You cant repeat the internet because it was one time - if the internet died and we had to start again due to what everyone knows we would not be able to recreate its dominance
