You're saying that as if Artemis III is going to be the first time Artemis eats delays.

What I'm seeing from Artemis recently is "good signs of life" rather than the opposite.

They acknowledged that Artemis III is "system tests" rather than "a full landing", which gives it far better chances of happening before 2030. They're trimming the fat deposits from the program by removing things like Gateway or NRHO. They're pushing for a more aggressive launch cadence. They're actually seriously bringing up "a persistent Moon base" and "manned flights every 6 months" as Artemis program goals.

This is more focus and ambition than what NASA had in actual literal decades.
