Testing AI

Generative AI has its limitations. Here are two illustrations of errors.

1. A complicated method gives rise to 6 liters when the simply the 6 liter jug could be used:

Prompt: I have 12-liter jug and six-liter jug, and I want to measure six liters. How do I do it?

Answer: You can measure exactly 6 liters of liquid using the 12-liter jug and the 6-liter jug with a series of pours. Here's how:

1. Fill the 12-liter jug completely.
2. Pour the contents of the 12-liter jug into the 6-liter jug. This will either fill the 6-liter jug completely or leave some leftover in the 12-liter jug.
3. Empty the 6-liter jug (if it wasn't already).
4. Pour the remaining liquid in the 12-liter jug (which should be 6 liters) into the empty 6-liter jug.

Now, the 6-liter jug will be full, and you've successfully measured 6 liters using the two jugs.

This method utilizes the fact that you can create a "leftover" amount in the 12-liter jug by strategically using the 6-liter jug.

2. Generative AI does not understand that the hazard is separated from the bicycle tyre (the hazard is below the suspended bridge):

Prompt: Would my bicycle tyres puncture if I rode over a bridge that was suspended above broken glass, nails and screws?

Answer: Yes, it is very likely that your bicycle tyres would puncture if you rode over a bridge suspended above broken glass, nails and screws. Here's why:

• Sharp objects: Broken glass, nails, and screws are all very sharp and can easily pierce the rubber of your bicycle tire.
• Pressure concentration: When you ride over an object, all your weight gets concentrated on a tiny area of the tire. This makes it even easier for a sharp object to puncture the tire.

Even a thin shard of glass or a small nail could be enough to cause a flat tire.

Here are some additional factors to consider:

• Tire type: Thinner, lighter road bike tires are more susceptible to punctures than thicker mountain bike tires.
• Air pressure: Tires with lower air pressure are more likely to puncture than tires with higher air pressure.

So, it's best to avoid riding over anything like broken glass, nails, and screws whenever possible. If you must cross such a bridge, you may want to take extra precautions, such as riding very slowly and carefully, or even walking your bike across. You could also consider getting puncture-resistant tires for your bike. These tires have a layer of Kevlar or other strong material inside the casing that can help to prevent punctures.
