I don't think Burry will pull things out of nowhere to voice his concern about. After all he did not make millions based on pure dumb luck.

My opinion: 

It's a case of "where there's smoke, there's fire". There's some problems, whether they're serious or not, especially if it really has to do with accounting, I would think it's best to fix it before it becomes problematic.

It might not be outright fraud, but understating depreciation to make the books like prettier is dodgy. After all these chips become outdated so quickly with manufacturers always looking to churn out the next bg thing.

Nvidia feels highly reactive these days, like they are seriously worried and threatened by externl noises, Burry's criticism, Google TPU. Feels a little iffy, or maybe that is their MO.

Honestly I think there is money to be made from the AI bubble popping, especially if these companies are becoming overconfident and reckless, leading the market to being overly enthusiastic about prospects.
