Andrew could have been more tactful in his blog post (though as I've grown older I often find less tact to be more effective), but it really sounds like accommodating Bun was a net negative for Zig.

  When Jarred joined the Zig community about 5 years ago, I described him as someone who had strong "beginner energy".

I wouldn't call it beginner energy, though I understand it might seem like that. Rather, it's an approach to development and no amount of time changes it.
