You can only become a dictator one time, after that you are a dictator.
So he’ll only “become” a dictator on day one, the rest of his life hell just be a dictator.
And let’s not entertain the fantasy that his heath will catch up to him sooner rather than later, remember he has access to better healthcare than 99% of the population and it’s entirely state funded.
We’ll be stuck with him for at least a decade, but I wonder who will inherit the throne when he’s gone?
