You have way more insight than the average non-tech person. You know who is big and a small fry in the game, know the trends. You read the tech news in the last 10 years. You have preferences and opinions.

I cannot say the same about say, agriculture, food or musical instruments.

So yeah, we have some kind of edge here.

You are not competing against the average non-tech person, but against professional investors that study the companies inside out, question the management, consult domain experts etc.

The knowledge you described is unlikely to give you an edge if you have never even looked at the companies' financials or don't know what a discounted cash flow is.

It doesn't take a genius or a DCF model to know that investing in Apple a couple years post-iPhone is a no-brainer. Momentum and trend based investing is just as successful as nerding out over numbers. You can simply be right in broad strokes and be successful - you don't have to get every detail right. It helps to have a long time horizon.

Sounds like hindsight bias. If it was a no-brainer at the time, everyone would have wanted to buy Apple stock and few would have wanted to sell, pushing the price up to where it no longer is a no-brainer.
