Let me preface this by saying, I will be more than happy to be proven wrong regarding it's completion in 2030.

High speed rail corridors don’t pop up overnight, and they take longer if you want it to be built as economically, safe, and well-thought out as possible.

I completely agree. When factoring the high cost, inflation, securing land rights, design approvals, legislation, funding, and the fact that "major components of the project (representing over half its cost) have no bidding or contract management experience. Thus, estimates for these are clearly suspect." Additionally, "The Authority does not have stable and predictable revenue at either the state or federal level, as discussed earlier in this chapter" in addition to "Costs for large capital projects are also defined as a range, due to variables that include several factors beyond the Authority’s control, such as future inflation levels and industry conditions." I acknowledge that you admitted to the issue of inflation, as well as them mentioning "Significant progress has been made despite this challenge." However, based on the reasons mentioned, along with several that are mentioned on their website and the Wikipedia page further reinforce that I am doubtful this will be completed in 2030. This isn't even considering unforeseen issues that may arise during development, management, and legislation. If anyone can also guarantee there won't be any disruptive events in the next 7 years, along with managing to acquire these funds, design approvals, acquisition of land rights, then I'll be happily convinced.

Once again, I will be more than happy to be proven wrong, because I have wanted to see this project completed for a long time now.
