The idea that blockchain programming should be done by anyone is pretty dangerous. The problem is that programming for an immutable ledger for applications that probably store currency and has a lot of business values is difficult. It requires a lot practical and theoretical background, programming skills and quality assurance. Non-statically typed languages, like Javascript provide the possibility for everyone to implement fast small programs, however the language will be very soon a problem as one wants to implement either large scale or mission critical programs. For such highly secure, highly mission critical applications very strictly typed languages with formal verification and strong testing methodologies must be used.
