Surely you don't mean actually permanent. So what time scale do you think they will last?

[tibbetts]

One reasonable perspective is they will be successful until there is a market correction so large it can't be hedged against. World War Three, global warming societal collapse, popular revolution, or massive antitrust activity.

As they say, "in the long run we are all dead."

GE has been in business for 125 years and is still going strong. Not unreasonable to expect the same for at least some tech companies.
