Not really, it's financing 101. If the cost of borrowing money is low then it's worth taking on debt to finance your growth. Once the rates rise you can service that debt (likely at ~1.5%) and reap the rewards on extend yourself with those low interest rates. You don't even need to be an MBA so see that value, even your dentist probably does it. If they can borrow 150k and increase the size of their clinic, they can then get more money from providing their services to more people. If you comment was more aimed at the amount, $77B, then keep in mind that it's far from a bad ratio considering the assets of MSFT at 107B that's 0.7 which is high but not abnormally high considering that we are coming out of historically low rates. Finally, there is such a thing as carrying too little debt, which is unsurprisingly a bad thing because it hinders your growth. Think about what MSFT did with that money. They hired people and developed new products to fight AWS and GCP if they hadn't done that, their rate of innovation would be lower and they would have fallen behind, slowing their future growth. Without cheap debt they likely wouldn't have given a ton of compute to OpenAI for ChatGPT which is now making MSFT look much better compared to Google and Amazon.
