I disagree. ChatGPT, at least v4 that I use, is simply fantastic for this type of back-of-the-napkin calculation. People lose out on its value with this type of pedanticism. Let's take your question, "Would you know better if it said 5b km?". Nope, I wouldn't have a clue - or care! ChatGPT informed me in SECONDS and 3-4 prompts that "At 2G constant accel/decel, it'll take ~8.5 days to get to Uranus, reaching a top speed of 2.3% of light speed (14.2 million m/s), and experiencing 17 seconds of time dilation." Even if each of those numbers were off by a factor of two, it still gave me a greater intuition for the problem space than I had before. I couldn't guess whether the flight time would be measured in days or years. With 4 prompts and 4 minutes invested, I had an answer within 11% (according to your sources, which I also didn't fact-check because it doesn't matter for this type of back-of-the-napkin work). I didn't hide the fact of where this information came from - I cited my source. My hope was to share this new intuition of the problem space I'd received, so that HN viewers wouldn't have to invest even the small effort I did to enjoy these fun back-of-the-napkin numbers. The answer of <9 days was shocking to me! Rather than banning intellectual curiosity and shunning use of our new amazing tools like ChatGPT/Claude/Bard/Mistral, I suggest we openly discuss and share our processes with each other. Who knows, maybe we'll learn something cool!

And for fun, and for future readers if the above ChatGPT link breaks, ChatGPT did "show its work" for the various calculations, which I think is super cool. Here's its Python code it used to calculate travel days: # Constants acceleration = 2 * 9.81 # 2G in m/s^2 distance_to_uranus_km = 2.6e9 # Average distance to Uranus in kilometers distance_to_uranus_m = distance_to_uranus_km * 1000 # Convert to meters # Distance for half the journey half_distance = distance_to_uranus_m / 2 # Time to reach halfway point (t = sqrt(2d/a)) # Using formula d = 1/2 * a * t^2, rearranged for t time_to_halfway = (2 * half_distance / acceleration)**0.5 # Total time for the journey (double the halfway time) total_travel_time = 2 * time_to_halfway # Convert total time from seconds to days for easier interpretation total_travel_time_days = total_travel_time / (24 * 3600) total_travel_time_days Here's its code for calculating the top speed: # Calculate top speed at halfway point (v = at) top_speed = acceleration * time_to_halfway # Convert top speed from m/s to km/h for easier interpretation top_speed_kmh = top_speed * 3.6 top_speed_kmh It's wondrous to me that LLMs can now execute code for such answers rather than just hallucinating their answers. I can't wait to see where this goes as AI gains access to additional tools.

I appreciate you removing your previous "So you posted a long whine" reply. > Nope, I wouldn't have a clue - or care! I find this just baffling right next to you talking about "greater intuition" or "intellectual curiosity". You don't care if your "intellectual curiosity" is feeding on complete misinformation? You didn't do any "back-of-the-napkin math" (I did, but you, by your admission, don't care), you just took a plausible-looking factoid and run with it. It's equivalent to believing the first SEO spam listicle Google returned and calling it "intellectual curiosity" — worse, in fact, because at least there is a slight chance of an actual human checking those listicle "facts". I believe the "process" you refer to is roughly: - pay for GPT-4 - type a question in - take the answer on faith - post it elsewhere without doing any work to verify it Is this correct? If so, I just don't think it's a good process. It also has no "back-of-the-napkin calculations" that you weirdly insist on, you didn't do a single addition in the entire "process".
