Bitcoin developers are ones which with the aid of proper education, training, research and practical work have helped in improving their skills and knowledge about bitcoin resulting to quality contribution to the bitcoin ecosystem, making it fast and efficient.
It is true, bitcoin developers have being increasing over the years but with recent happenings, don't you think bitcoin need more developers?
If you mean by recent happenings being more adoption and more complicated issues then yes I think more developers are necessary. Not only in quantity but also in quality. Bitcoin is growing more and more each year and we need to constantly develop bitcoin to keep up with the number of investors and users.
I have no doubt many would emerge as developers of bitcoin as kids nowadays are much more interested in bitcoin and tries to pursue careers in development.
I think they should be sent in badges to areas where bitcoin haven't been heard or where their is no knowledge about digital gadgets or have access to the internet.
Sure but this will prove to be a challenge. Logistically speaking and not to mention the financing part. This will be complicated but with a lot of planning and organizing then it can be arranged.
