Not surprising, but Jarred has been teasing "tomorrow I swear" for months and Bun keeps missing his own deadlines.

There's clearly something wrong in their confidence about Rust Bun: If it isn't ready they should have said "whenever it's done", and if it is they'd have met some deadline by now. I suspect the speed was supposed to be part of the stunt, yet they seem to have encountered the 90:90 rule.
