The ellipsis, represented by three dots, can be viewed as a perplexing and unappealing subject for in-depth study, as pointed out by Lynne Truss in her book "Eats, Shoots & Leaves." The idea of pursuing a PhD focused on such an ambiguous punctuation mark raises concerns about the practicality and relevance of the research. Truss expresses horror at this academic pursuit, suggesting it could lead one into a metaphorical 'black hole' of obscure knowledge.

Furthermore, she emphasizes the uncertainty of securing a job after investing three years in studying a seemingly trivial aspect of punctuation. This critique highlights a broader issue within academic circles where niche topics may lack real-world applications, leaving scholars questioning the value of their specialized focus in the job market. In this way, Truss’s commentary serves as a cautionary tale about the risks of pursuing overly esoteric academic endeavors.
