There are plenty of non-US index funds, like EU, UK, Japan and others. There are also indices that track smaller companies rather than just the S&P500 or Nasdaq.
Or diversify in both directions - small US, and big and small international funds.
There are other companies than the magnificent 7. Other boring companies with boring dividends and solid earnings that have nothing to do with tech. Ulta. Pepsi. Chevron. But you sound pretty smart so I’m sure you had a good reason to invest in non us markets.
It's plainly obvious where all of this is going.
