The other side of the argument is that the more people that are creating/working with and disseminating/peer reviewing crypto projects, the better we will be educated on crypto collectively.

An example is web technology: plenty people have made plenty html/css/js mistakes in the past but there is also an overwhelming amount of evolving best practices on this topic, no doubt because of the mistakes made before. If all we do is decry crypto is hard, don't roll your own, then no one would be learning anything, and cryptography will be left to the a few select mathematicians and organisations that are referred to with acronyms.

It should be: crypto is hard, learn it and experiment with it, share your thoughts, and don't roll your own for critical applications.

Edit: clarity of argument in my example and grammar
