The best in the business are often the very last to see it coming

In 1984, the head of Digital Equipment Corporation, then the largest maker of mini-computers in the world, described the personal computer as cheap, short-lived and not-very-accurate machines. He said it with confidence, and he wasn't a fool. Digital had itself been the upstart decades earlier, breaking into a mainframe world with cheap, simple machines that the giants of the day dismissed the same way he was now dismissing PCs.

Andrew Grove calls this the inertia of success. Managers rise to the top of an organization because they were good at something in particular, and once there, they keep leading with that same strength, the way a batter who has hit for years off a certain pitch keeps swinging the same way even after the pitcher changes speed. Charlie Chaplin, still making silent films in 1931, said of talking pictures, I give the talkies six months more. He held out for years on sheer talent before finally surrendering to sound dialogue in 1940. Seymour Cray, the man whose name was practically synonymous with supercomputers, saw his own company run out of money as both the technology and the government funding that had defined his industry shifted underneath him at the same time.

Grove suggests that the emotional sequence a company goes through when its world changes doesn't look like ordinary grief. It starts with denial, the quiet insistence that if just one thing had gone slightly better, none of this would be happening. Then comes something subtler: escape. Executives whose core business is under threat often throw themselves into seemingly unrelated acquisitions, board memberships, or pet projects, activities that legitimately demand their full attention and let them avoid the harder, more painful question sitting in front of them. Grove admits he wondered, looking back at his own choice to spend real time writing a book in the years just before Intel's biggest crisis, whether that too had been a form of escape.

Only after denial and escape does a company, or a person, arrive at acceptance and the harder work of actually acting on what has changed. Grove's warning is that the people most likely to get stuck early in this sequence are not the weak performers. They're often the ones who were most rewarded for doing things the old way, which is exactly what makes letting go of it so difficult.

Pay attention the next time confidence starts sounding a little too much like denial, the kind that explains away a pattern of bad news by pointing to one small, fixable factor. If you notice yourself, or your leadership, suddenly pouring energy into some unrelated project, acquisition, or side venture while the core of the business struggles, ask honestly whether that's real strategy or a comfortable escape from a harder question. Try naming the exact skill or approach that made you successful in the first place, then check whether you're still leaning on it simply out of habit rather than because it's still working. And don't wait for undeniable proof before you act, because the people who cling longest to what once worked are usually the ones who pay for it most.
