>Before claiming he is stupid, you need to read the balance sheet

Before you tell someone they need to read the balance sheet, you should read the balance sheet.

Tesla has $3.5BB in cash, which they are burning through at the rate of almost $1BB a quarter, and have $4.1BB in accounts payable. Those are "bills", and their cash doesn't cover that amount, let alone the long-term debt payments.

They've been accumulating cash by letting their bills pile up; this figure grew over $1BB quarter over quarter.
