Exactly, who knows what will happen in the next few months or years to come, who knows there could be another satoshi building a mind blowing technology some where in the world, the only thing we know is that there is room for growth and possibilities, this leading technologies of today may not be in the next couple of years to come, only thing is enjoy the present and hope for a better future.
Yes i'm sure about it, in fact more than one to my knowledge. No the thing is pretty simple:
- Don't fix what isn't broken
- Don't innovate with something that was made for innovation and won't need any help
If those Satoshi's have a decent enough view of everything and someone so smart does of course, then they will invest their time and energy building something that really needs help. For example, self-driving cars, robots, electric cars, environmental-friendly ways to generate electric power.
Issues of the world that still need to be fixed and which are in a much worse state right now, some worse than the others.
