[SomewhatLikely]

I've felt the same way over the years, though my belief in that maxim is fading for at least two reasons. One, is that if you're going to extend beyond index funds, it's probably best to invest in companies/industries you know best. And secondly, "tech" is a very broad industry, and there's no reason to think it couldn't come to be a larger and larger share of the whole economy. "Tech" is set to continue disrupting industrial, transportation, agricultural, and energy sectors. I think when you look at it that way, it's almost foolish to avoid tech. Oh, and I'll add a third: would you rather invest in something that is growing, or something that is stagnant/dying?
