Arrange the following into a meaningful sequence:
1. I’m not sure when I first became aware of the Singularity.
2. In the almost half century that I've immersed myself in computer and related
technologies, I've sought to understand the meaning and purpose of the continual upheaval that I have witnessed at many levels.
3. Gradually, I've become aware of a transforming event looming in the first half of the twenty first century.
4. I'd have to say it was a progressive awakening.
5. Just as a black hole in space dramatically alters the patterns of matter and energy accelerating toward its event horizon, this impending Singularity in our future is increasingly transforming every institution and aspect of human life, from sexuality
to spirituality.

1 introduces the author's uncertainty about when their awareness of the Singularity began and 3 builds on the first one, indicating that the author's awareness has developed gradually, and it specifies that the transforming event (the Singularity) is expected in the first half of the twenty-first century. 4 further emphasizes the gradual nature of the author's awareness, describing it as a "progressive awakening". 5 expands on the analogy of a black hole, drawing a parallel between a black hole's impact on space and the Singularity's transformative effect on various aspects of human life. 2 provides background information, explaining that over almost half a century, the author has been immersed in computer and related technologies, seeking to understand the meaning and purpose behind the continual upheaval witnessed.
