I can't comment on Herb Sutter. But Jonathan Blow, from what I've seen and heard, is deeply passionate about the domain Jai is targeting and appears to have Jai already in pre-production use in his next in-development game/engine. I agree about the MVP stuff; in contrast to things like Zig, Jai is the completely opposite, it's being built behind closed doors with little to no community feedback, with the creator and inner circle have say in the direction. I'm not sure how well it will pan out. Seems like, from the outside, Blow is scratching his own itch and maybe it's possible Jai will never take off. The only real world similar example is Elm, which while open source, is/(was?) also heavily design behind closed doors in many ways, albeit not to the degree to which Jai is. There's also Mojo, the Python-like language. It's also being built behind closed doors, but it seems to have a lot of hype behind it already.
