The $5 trillion didn't come from nowhere. People spend money on the products because they are helpful.

However, you're right that most people at these companies are so accustomed to the "free money faucet" from ads, huge margins, etc. that it's incredibly easy to end up totally disconnected from reality. That's probably what frustrates you the most.

I will say - after having left Google just about a year ago now - that there is literally no better time to make money in tech than right now. AI is eroding the moat of all large tech companies, and skilled individuals with passion and drive can make a huge impact on the world with an incredibly small budget.

You'll make it. All of us will.
