In the presence of a disruptive innovation or evolution lies uncertainty. The fact that blockchain technologies like Ethereum came into existence shows we progressing as a human race. There will only be one thing that meets this, and its is improvement which might cause some former improvement to be phased out or become secondary.
However, we should only continue to analyse and weigh in on how the technology may improve and its only going to get better from there. Take for example the advent of social media prominence. There were different drawbacks along the line and more drawbacks still exist and more to come.
What am sure of is that the blockchain technology is here to stay, only to be decided is its major flagbearers. Only time will tell. Peace my steemit folks.
