My negative bias comes from having attempted a hardware development project in the past, with similarly ambitious and optimistic time frames, only to have reality kick in and demoralize the team by having the project drag on and on far beyond our projections (but well within industry norms).

I think it's an awesome, exciting project that the world wants to happen. But if it turns out that the original timeline is skewed heavily toward irrational optimism, it may be demoralizing to those involved to have their expectations repeatedly quashed. However I may be wrong here, because if the supply chain company that's involved is being realistic and has experience, I may be the one who is off-base about the timeline.

(I posted more details of my experience on the main thread).

I agree with you that a lot of comments on here are negative without adding any value, ie. no new data / insights, just content-less, emotional pessimism.
