knows me extremely well, is able to tirelessly work on my behalf, and has a personality tailored to my needs and interests.

Today's LLM's marketed as the future of AGI are more focused on knowing a little bit about everything. Including a little bit about how MRIs work and a summary of memes floating around a parody subreddit. I fail to see how LLM's as they are trained today will know you extremely well and give you a personality tailored to your needs. I also think commercial interests of big tech are pitted against your desire for "tirelessly work[ing] on my behalf".
