You are shifting what you talked about. The comment I replied to was about tech companies putting money into stock buy backs instead of AI. You are no talking about AI being a bubble.
You also failed to understand that money put into an investment has to go somewhere pretty much immediately. If someone defaults on a loan they must have used the money, so someone else has it, so it is still not destroyed.
If this was true universally then the total amount monetary value in the economy was constant, apart from the feds printing some. But it's not. Value comes and goes. You can definitely lose money without it going elsewhere.

I explicitly did not talk about AI being a bubble.
You may understand of economics (at least you say so). But reading comprehension is not your forte.
