Religions within humanity is grounded on the DNA based
existential crisis which is inherent and unavoidable within the psyche of the individual.
The future of religions, thus will depend on how the individual[s] and the average are able to manage and modulate this inherent and unavoidable existential crisis.
The point is, Islam as a means to deal with the existential crisis via a promise of salvation to paradise with eternal life is fraught with lies, falsity, evil and violent elements culminating in such consequences;

With increasing communications of the truth and rationality, soon the inherent falsehoods, evil and violent of the ideology of Islam will be exposed. From this, ex-Muslims who are still affected strongly by the existential crisis will shift to Christianity, the more pacifist religion.
Christianity is optimal at least till the next 50 years but it has its pros and cons.
When the cons of Christianity outweighs its cons [say after >50 years], the majority will shift over to Buddhism and other pacifist & effective religions to deal with the inherent and unavoidable existential crisis.
When the cons of these pacifist religions outweigh its cons [from institutional elements] the majority [says >100 years] will shift to a generic sort of spiritual-proper that is fool proof to evil and violence to deal with the inherent existential crisis. This is possible given the current increasing trend of the exponential expansion of knowledge and technology to evolve the human mind to higher levels of moral grounds and wisdom.
This will be the end of religions especially institutional religions.
