re: VOO or QQQ

I'm not young, and TQQQ is my largest holding, so you won't find me arguing against a young investor with a high-risk tolerance doing the same. One common assumption by nay-sayers of TQQQ is that people can't handle the emotional rollercoaster of TQQQ. They assume people won't hold when the price drops drastically (as it has) or that people won't buy more shares when the price drops. If you have the fortitude and means (or planning) to do those things, then taking a long view, I think TQQQ is a no-brainer.

Texas Tea points to interest rates being the 'sole driver' of QQQ's performance. I don't see it this way. Indeed, the price of tech stocks is greatly affected by interest rates due to the discounting of future profits. Low-interest rates provide an environment for all companies to do business more efficiently and do it cheaper than they would otherwise. Low-interest rates do not explain the growth of tech stocks over a decade.

These companies have grown because they have changed the future with their inventions. They have created markets for new products and services. They have provided productivity gains and have been rewarded for those activities. Automation and AI have only just come onto the scene. I wouldn't bet against them.
