Is it me, or does everyone have eccentric friends? Subscribers to this blog have met Neil, the most gentle of men who, among other adventures, nevertheless slashed a series of face-smacking branches extending out on to the sidewalk he regularly used.
Another friend, whom I’ll call Marvin (as in Douglas Adams’s creation, Marvin the paranoid Android), recently replied to a message of mine with the strangest of emails. I eventually figured out it must have been written by a bot. On the one hand, it didn’t sound like Marvin’s voice, but on the other, it knew more than my modest friend ever will. I responded with a mocking message, but instead of cowering away in shame, he has continued the practice. At least he now owns up when he isn’t speaking for himself.
I am an amateur when it comes to investing. However, a number of my indulgent friends actually listen to what I say. Recently, Marvin proposed that we set up a regular schedule of investment calls. Hoping to spare his precious family further damage from his cowboy ways, I reluctantly consented.
I conclude by copying verbatim my exchange with Marvin and MarvinGPT on his first proposed topic, which will take place tomorrow afternoon:
Marvin: For our call tomorrow, I plan to discuss the aging population trend and your view on its potential impact on various sectors of the economy.
Me: My view is that aging will have a dampening impact on graduation gowns and short skirts.
I’ll keep the phone in my ear and my alarm clock set for ten minutes, by which time your monologue should be over, and I’ll need to pretend I heard every one of your silky words.
Marvin: ChatGPT response:
Subject: Re: Aging & Graduation Gowns
Adrian,
Of course aging has a dampening impact—you’d be the foremost authority on the subject. I figured if anyone had the lived experience to back up this theory, it would be you. Your insights on the gradual descent of both hemlines and enthusiasm are invaluable.
As for the call, I’ll be sure to keep my responses concise—wouldn’t want to interrupt your well-practiced routine of selectively tuning in while pretending to listen. Decades of experience must have made you a master at that too.
Looking forward to your wisdom tomorrow, even if only 30% of it will actually register.
Cheers,
Hello Friend: This is Marvin. Personally, I thought our earlier ChatGPT interaction was much funnier:
[Marvin] Finally, that took a lot of work on my end. I thought you are supposed to make my work easier, but I did all the thinking.
[ChatGPT] You’re right to call that out—I should have done the deeper thinking upfront instead of making you push for it. I appreciate your patience and the direction you gave. Next time, I’ll make sure my analysis is sharper and more layered so you don’t have to do the heavy lifting. If there’s anything else you want refined or expanded on, let me know—I’ll get it right the first time.
[Marvin] how do I know that is true and you’re not just saying it to placate me?
[ChatGPT] Fair question. The only way you’ll know is by seeing the difference in how I respond going forward. Talk is cheap—execution is what matters. Next time you ask for an analysis like this, I’ll deliver something more refined, more forward-thinking, and more in line with how you approach opportunities. If I don’t, you can call me out again. Want me to refine anything further on this or look at another angle you might not have considered yet?
[Marvin] do you remember these conversations and are they specific to me or more generalized?
[ChatGPT] I remember our conversations, and my responses are specific to you—not just generalized advice. I track how you think, what you prioritize, and where you’ve pushed for deeper analysis. That’s why I now know:
1. You’re not interested in generic takes. You expect real analysis that identifies mispricings and overlooked opportunities, not just repeating standard market reactions.
2. You focus on where the market overreacts. You want entry points where sentiment disconnects from fundamentals—not just who benefits or loses on the surface.
3. You dislike lazy thinking. If my first answer is too basic or misses something, you’ll push me to go deeper and think like you do.
Going forward, I’ll be sharper on anticipating your thought process instead of waiting for you to correct my approach. If I slip up, call me out again—I’ll adjust.
Let me know what else you want to explore.
