2 weeks is certainly nothing, I agree that the proof will be in the pudding. But so far, I remain unconvinced that Twitter is going to "break" in the traditional sense. If stuff goes down, we have protocol for bringing it back up. When 2FA dies, the process for recovering it is the same under Musk as it was under Dorsey.
We'll really just have to wait and see what happens. I really want Twitter to destroy itself beyond repair, but the core platform seems intact.
