If you produced a car, must you be there before anyone can be able to ride on such car, what is the essence of the manual and those who are experienced in driving to teach you thill you understand, if you're expecting that Satoshi should think and act as you do, then you're completely wrong because he made bitcoin for everyone to use and is there somewhere probably watching every human efforts and activities towards the adoption of bitcoin, as you can see, people are adopting continuously without having to encounter seeing Satoshi.
You just made me smile, you made a lot of sense anyway because inventors do introduce things and even die off the surface of the earth not to talk of someone who said he want to focus on other things. So he still wants to be more creative and innovative that is why he wants to try something new.
He also have other things which he plans to achieve, just like he created bitcoin. He does not need to stay focus on bitcoin anymore, because he has created it and left it open for anyone who is interested to work and improve the technology for better security, which we have people doing that already. Moving to other things like he said shows that he gat a lot to do as someone who has great innovation. Bitcoin is speaking for itself and doesn't need any advert.
Sure he has other things to achieve and he must be someone of great intellectual capacity that is why he also want to focus on other things in other to bring more solutions to human's problems. Wish he can create something as innovative as these again so that we can take path in more of his innovations.
Let's all be thankful that Satoshi created this innovative technology that probably changed the lives of majority of the people who know and take advantage of its uses. It can either be a currency; or as a form of investment.
That is the most important thing, creating this modern day digital technology is the best thing that happened to anyone in this 21st century because it will surely stand the test of time and our upcoming generations will inherit this innovation and be proud of us that we also took part in it's success too.
