Apple's Biggest Change in 20 Years: A Shift to Custom In-House Silicon

Apple has undergone a major strategic transformation over the past two decades by moving away from off-the-shelf components in its devices. The company has instead focused on developing proprietary, in-house technology to power its products. Custom silicon has emerged as a central pillar of this approach, aimed at boosting performance and deeper hardware-software integration. Apple hardware engineering chief John Ternus spoke about this shift in a recent interview, describing it as one of the most profound changes at the company.
