Yes. Based on my experience with large projects developing new concepts.
At 5 years after converting to RUST is the point where I would be worrying if it wasn’t at mid to late beta testing/production. But even then there maybe some very good development reasons for such a delay.
We are at around 2 years since Starting RUST conversion and we have code working and development accelerating.
You will find that most if not all other crypto projects have money at the core of the motivation for Quick deliveries (even if not good code). You also see a lot of pushing from those who want to convert their coins into large profits. The best projects are ones that allow the developers to develop rather than produce results.
Have a look at microsoft, they pushed out code, missed multiple deadlines for each OS and the OS is more rushed coding rather than getting it even close to good programming. Full of bugs and the users feel like they are paying to be bug finders.
And to answer why there is not more money. Because those with the extra large money do not want to see a version of the internet that they cannot collect information on everyone. They want control and earn more money off the people (& their info). Microsoft could give away their O/S and make more than enough off their other products that use Windows O/S. But no even charities have to pay for the O/S from 2nd hand computers given to them.
