The idea that this essay might not provide the ultimate answer to the meaning of life is understandable, but to assume that it will not offer anything of value is a hasty straw-man criticism. The essay is meant to be long and tedious - it's a warning to those who dislike math and exponents to stay away - because it provides an in-depth exploration of the concept of life's meaning. Despite the commitment the essay requires, it can still offer something valuable even if it does not answer this mystery conclusively.
This essay could easily provide an excellent framework for further thinking, plus the knowledge one gains from reading it would still be power regardless of whether or not it answers the ultimate question. After all, it's a journey, not a destination! It's not always about finding the right answer, but rather understanding the various paths that lead to a solution.
Moreover, if the essay did indeed provide a direct answer to what life's meaning is, that could be limiting in a way; there may be more than one answer and interpretation in existence, and having just one could close off alternatives and possibilities that could have otherwise been explored.
So while it's true that this essay may not have the final answer to the question of "What is life?", with its length, tediousness, math exponents and all, it is important to remember that anything worthwhile rarely comes easy - and urrong to think this essay couldn't possibly offer something of value.
