It is absolutely a different company. I had the opportunity to intern there twice in the late 70's and then was acquired by them in 2015, the IBM of 1978 and the IBM of 2015 were very different businesses. Having "grown up" so to speak in the Bay Area tech company ecosystem where companies usually died when their founding team stopped caring, IBM was a company that had decided, as an institution, to encapsulate what it took to survive in the company's DNA. I had a lot of great discussions (still do!) with our integration executive (that is the person who is responsible for integrating the acquisition with the larger company) about IBM's practice in terms of change.
