Thanks! I write about this briefly in the blog post, but the more detailed answer is there's no need: Zig's grammar is simple/explicit/powerful enough that they pick it up themselves in a weekend. Learning Zig is just not something we need to talk about with new hires, and we hire systems programmers from all backgrounds.
To be clear, we do invest in months of onboarding in terms of understanding the TigerBeetle code base. For example, matklad has recorded nearly a hundred hours' worth of IronBeetle episodes [0].
But I just noticed at one point that people were joining our team and never having any trouble with Zig. The question was just never being asked. Essential simplicity is a great benefit!
