 We don't need precision to see the big picture. Think of something that AI can't do right now, then wait and see how long it takes before it can do it. 
 Things it can't do, or ideas it can't create? 
 Personally I've just been picking big things that "AI will never do". It's tempting to pick physical tasks since these are so easy for us, but you'll see the trend faster if you pick something mentally difficult. Academic, creative, logical, whatever. 
 Current AIs can't *think*?

As in: take information as a foundation and then use logic combined with this information to come up with answers to questions.

As far as I know current AIs are merely capable of producing texts that would have a relatively high probability of being uttered by a human, based on the training data. Maybe that is somewhere on a shared spectrum with thinking/reasoning but it's far away.

Or did I miss something and there are AIs that differ significantly from the LLM approach? 
 Given their framing as "predicting the next word", that's a common expectation. The mistake is seeing the interface as the implementation. In a way "predicting the next word" is how people talk as well, so to know how "intelligent" an LLM is we need to see whether they can predict something that is reasonable but not obvious:

> My car gets 30 miles to the gallon and currently has 2 gallons of gas. Gas is currently $3/gallon. How much money do I need to drive 100 miles?


Let's approach this step-by-step:
First, let's calculate how many miles we can drive with the current gas:
The car has 2 gallons
It gets 30 miles per gallon
So, 2 gallons × 30 miles/gallon = 60 miles

Now, let's see how many more miles we need to drive:
We want to drive 100 miles total
We can already drive 60 miles
So, we need to drive an additional 100 - 60 = 40 miles

Let's calculate how many gallons of gas we need for these extra 40 miles:
The car gets 30 miles per gallon
So, 40 miles ÷ 30 miles/gallon ≈ 1.33 gallons

Now we know how much gas to buy, let's calculate the cost:
Gas costs $3 per gallon
We need 1.33 gallons
So, 1.33 gallons × $3/gallon = $4
Therefore, you need $4 to buy enough gas to drive 100 miles.
