>the default bubble is potentially a lurking time bomb
Many things are potential lurking time bombs. I can't think of a single period during any bullish market where you could not point to something and claim that that could be a potential end to the bull run.
The problem is when you are in the business of making predictions, if you just scream "Bear" long enough, eventually you'll be right and then you can write a book subtitled, "By the man who called the 2021 (or 2022 or 2023 or 2024 ...) stock crash" and people think you're some sort of genius.
