Realistically, and assuming I claimed it and handled the financial and legal aspects of having that much money, I’d do this;

Pay off my debts, as well as those of my parents and sister, then help friends pay off everything. Then buy a nice house and nice stuff, leave my job, then travel.

Then I’d see what sorts of things I can use my money to improve, or who I can help.

While money is nice for security, I don’t need or want anywhere remotely close to 1$billion at one time. That amount of money is dangerous.

Bluetooth and nfc audio codecs have gotten so good that unless you’re running high impedance headphones with an amp/dac, wireless is effectively indistinguishable from wired, at least for most applications, and especially if using a mobile device.

It’s very simple. It’s because people falsely mistake freedom of speech for freedom from consequence.
