Bro, same can be said of large ecosystems we grow previously too. There was lot of delays (given our bureaucracy) in number of projects regarding rocketry, missiles and final tier space application especially....in the 70s and 80s.
But look at them now. There are lot of examples just like that.
They take decades to mature sometimes....given the intent to have as large capacity with us as possible to take forward.
But once they are matured, the time is shown to be quite worth it.
When it is multi-input system (like an aircraft given engine for such is itself a world of RnD on its own), the times can be longer.
