A decade is literally 10 years... So unless 29 now equals 40 then it is 3 not 4 decades

So let me get this straight, Copilot (Microsoft AI), Gemini (Google AI), and Meta (Facebook AI) all got the answer wrong? Like I said unless 29= 40 it is NOT almost 4 decades IT IS ALMOST 3 decades.
.... Wow seriously I know I'm late but I have to respond to this so at 9 years old you are 1 decade old? At 10 you've started your second decade, at 20 you've started your 3rd decade and at 30 your in your fourth decade? 1 decade = 10 years so unless a newborn is 1 decade old your logic fails. Since as you see above by your logic 10 would start her on being 2 decades old.... In reality (feel free to ask a professor or look it up anywhere) the first decade would mean she reached 10 years old, 2nd decade starts at 20, 3rd starts at 30 and 4th starts at 40... Which means saying a 29 year old is almost 4 decades old is most definitely incorrect...
Websters dictionary definition
"a period of 10 years"
As an example they use the following
"The decade of the 1920s runs from January 1, 1920 to December 31, 1929."
The reason this is accurate is 1 day more from December 31 is January 1st which would mean it is no longer 1929 but the year 1930 meaning at 29 ahe is under 3 decades old. Lets count by tens shall we? 10, 20, 30 (so 10 * X = 29? Answer? 2.9 which is ALMOST 3... Not almost 4
Your first year of life ends when you turn one year old. At one year and one day, you are in your second year of life. Your first decade of life ends when you turn 10, and then you enter your second decade of life. Making some reasonable assumptions, everyone reading this is in their first century of life, and most of us will not see our second.
We see this more often with smaller time frames. If you're in your first semester of college, you haven't finished it yet. She is 29. She is almost three decades old, at which point she will enter her fourth decade, because she'll be done with the first three.

The keyword here is "nearly in", that is to say nearly starting her fourth decade. Once you reach 30, you have 'finished' living for 3 decades and you start your fourth. It's kinda like how we are in the 21st century even though the 2000s, relatively speaking, just started and it is no where near the year 2100 yet. Semantics, i know, but thats just how english works sometimes
Edit: also, its troubling that people are starting to rely on ai for trivial matters like this. It's like giving up on thinking all together and asking someone to just hand you the answer
Besides, GenAI is in and of itself not infallible and there is always a non zero chance that it they generate a wrong answer
if you have ever seen ai generated images/artworks you know what i mean
"Once you reach 30, you have 'finished' living for 3 decades and you start your fourth" (Yes exactly) however at 29 they are saying she is almost 4 decades old not "Starting her 4th decade" she wouldn't "Almost be" in her 4th decade until she was 39 that is why I said the information in the gane was incorrect
Apologies for reviving an old thread, but your argument here is incorrect. They are not saying that she is nearly 4 decades old. Instead, they are saying she is "nearly in" or in other words about to start her fourth decade (which begins the moment a person hits age 30). If they meant to say that she was almost 40 years old, the sentence would be more along the lines of: "nearly at the end of your fourth decade".
You are focusing too much on what a decade is and missing the context of the entire sentence
A decade is simply a period of 10 years. The word 'decade' itself does not have any inherent positional meaning. Ergo, your understanding of the word is incorrect. The start of a 10-year period is in fact year 0. The 10th year would mark the end of that decade; not the start.
That said, I don’t believe there’s anything more I can add that would change your perspective. So I’ll leave things here
