Investing in T-bills is always a safe investment (well, provided you think the US will be around to continue backing them). The return is about the same as a high yield savings account, making them basically a savings account for the rich or for organizations that have more money than a simple savings account at a bank would support. I mean basically a large percentage of the money you put in the bank, the bank is turning around and buying T-bills with. I don't know if they are really worth investing in for normal poor guys like you and me, but then again, if you have a lot of cash, don't trust the banks, and want to park it somewhere stable but with a little gain, they are worth looking into.

I think the cyber truck looks so ridiculous....
