Starship is very close to being able to put next gen Starlink satellites into orbit ("very close" as in most likely within a year or so). Once that happens, it's over, there will not be competition for at least a decade. Before Bezos and others (and/or EU/China) build their own Starship copies (and if you've seen recent EU/China concepts, you can't call it anything else...), it's going to be the 2030s.
