Worked with the SB guys briefly and my take on it was that they're willing to stack the chips higher than anyone else. And if gravity gets in the way they'll keep stacking until gravity no longer applies
Despite the mockery and we work drama I reckon their all or nothing strategy is sound. If this project fails it'll probably be concurrent with a SV collapse in which case does it even matter?
If you're gonna take risks that involve catastrophic failure anyway you might as well bet big on upside
