Apple may be out of danger regarding the semiconductor chip shortage, but without overhaul to the supply chain many more companies could fail, reports CNBC.

The semiconductor chip shortage is old news, but when the second-largest public company in the history of the U.S. stock market says it just left $6 billion in potential sales on the table as a result of limited chip supply — as Apple just did — it reinforces why the U.S. economy needs to rethink how it sources its semiconducting technology so that doesn’t happen again.
