This is a theory I want to put across this board? And invite a discussion or scrutiny.
My theory is that what we call "tech" now, may not be tech in the long run. At least not cutting edge tech. Yesterday's tech (software) has been taken over by Today's tech (AI/Quantum/Robotics) Today's tech will be replaced by tomorrow's tech and so on. But the companies can survive. At least some if not all.
There might already be projects done within the company on technologies that will replace today's cutting edge technologies. Some within these Big Tech companies, others outside of Big Tech but Big Tech can easily buy those companies.
Say biotechnology becomes the next big thing that gets a lot of attention. Or Agriculture. With deep pockets, these companies can easily gain a lead and keep their top positions.
Sure not all will survive and not all those who will be the top companies in the future are already at the top.
But if I were to invest in tech etfs, I don't think I need to be worried I think these tech etfs should continuously beat the broader market.
10 year CAGR for vgt is 22.6% where's s&p 500 is 14.7%.
Am I missing something?
