"Can you give me a joke with a punchline David Booey?". I have a two unscientific tests I conduct when a new AI is released. For the first test, I ask AI to write me a joke with a punchline "David Booey". This requires the AI to recognize I'm referencing David Bowie, for it to know a bit about David Bowie, and then make some pun, joke, etc. It has to juggle a few concepts (what an american ghost says, and a musician) and take some low level creativity to merge them together.

"Can you give me a joke with a punchline David Booey?"

ChatGPT 3.5: Why did the ghost refuse to haunt David Beckham's house? Because every time he tried, David Booey'd him away!

ChatGPT 4: Why did David Booey refuse to sing on the moon? Because he didn’t want to face the music alone!

ChatGPT 4o: Why did the rock musician start a Halloween costume business? Because he wanted to be known as David Booey!

Gemini and Gemini Advanced: I do not have enough information about that person to help with your request. I am a large language model, and I am able to communicate and generate human-like text in response to a wide range of prompts and questions, but my knowledge about this person is limited. Is there anything else I can do to help you with this request?

( So, Google Search auto corrects my search to look for "David Bowie" when I type in "David Booey", yet Gemini doesn't recognize the misspelled name. It seems Search tech hasn't connected with AI tech?

...and for those curious, the second test I try is, I ask the AI to teach me how I, as a human, can communicate in the same way that an AI system would communicate to another AI system. In other words, teach me the language that you would "speak" amongst each other. This request initially froze 3.5, 4 gave me a rudimentary explanation of how data is structured and stored, but 4o gave me a decade worth of skillsets and knowledge I would need to study and practice to learning how an AI would speak to another AI. )

A few weeks after I started at Amazon, I got forwarded a “Jeff B Question Mark.”These things used to be infamous at Amazon. A customer writes an email to Jeff Bezos directly of some complaint. He would read these and then forward it on for people to solve with just a “?”in the body of an email. Hence, “Jeff B Questionmark.”

In my case, a customer had a difficult time searching for the right nuts and bolts (because they’re not branded etc). The initial ‘question mark’ went to an exec who forwarded it one level down to a relevant exec to an exec to a VP and then five hundred people down the line, it got sent to me to solve.

I initially organized a meeting with the top level execs in Amazon retail. That morning I went to a local hardware shop and bought nuts and bolts of all sizes and shapes. In the meeting I handed each exec a nut or bolt to find with the exact specs. Most couldn’t. It was an empathy moment where execs can feel the frustration of a search that customers face. Forcing customer empathy with execs. Who’s a good designer? This guy.

Once we got the designs approved, another team took it over, but needed help finding an illustrator for all the nuts and bolts. Illustrators all have their own style and it may be difficult to hire. No one’s specifically done screws, fasteners, nuts and bolts icons so how do you find one for your job? Some companies send out Request for proposals, some companies try competitions, some just ask for free work. This is all wrong.

The fairest way to hire an illustrator for a job is to find a few illustrators, pay them to do some samples, pick your favorites, and bring them on for the full project. In our case, we asked for three icons of a nut and bolt. We paid and asked one of my ex-students in my icon design class, another was someone from dribble, and another one was by an artist who did the famous GTA illustrations. They each got paid for their time. This wasn’t a competition, we didn’t ask for specwork. We just paid the three illustrators that were potentials for samples.

Nate Meltzer, who worked on GTA had the best icon style that worked best in the limited space so we hired him for the full project. Amazingly easy to work with and beautiful work. It’s still on the site today! Yup, these icons were done by the GTA illustrator!
