Is buddha's paths corrupt as no one attains the goal nowadays? (or are they?) Anyone reaching nirvana in recent years?

People practise buddhism for many years but no one achieves nirvana. No one reaches anātman (pali: anattā). The only theories Buddhism offers are anātman, nirvana, and the five aggregates, so my question is this: Is the Buddha's path corrupt, because no one achieves the goal?
Since many do not talk about attainments it is difficult to ascertain who has reached Nirvana, but there those who have practised fully would have realised it. This is a conjecture on can reach by taking the 1st few steps one reaches certain milestones in the path.

If you consider more milestones than the final goal itself there would be many more people who have reacht it.

Some milestones one would encounter are as follows:

Ones own practise will reveal to you what as further one practices more milestones are reached.
