The 30 years guess is based on the history of vancomycin, which like teixobactin was isolated from a soil bacteria. They presume, based on multiple similarities and things like teixobactin producing bacteria not having innate immunity to it except for not having cell walls, that it could have a similar period of freedom from resistance development. And if their thesis and what they think they know about it is correct, it could have an even better experience.
