No Defaults | Article | Alfred Lin (Sequoia Capital)

"Defaults are the quiet architecture of how we think and operate. They reduce friction, conserve energy, and let us move fast without having to reconsider every step. Without them, we would stall due to cognitive overload. With them, we rarely stop to ask whether they still make sense, and that’s precisely the risk."

Lin illustrates this with well-known examples: BlackBerry dismissed the touchscreen iPhone because their default said professionals needed physical keyboards; Kodak invented the digital camera but shelved it; Blockbuster passed on Netflix. These weren't ignorant companies — they were well-run ones whose very discipline reinforced outdated assumptions. As Christensen noted, good management can accelerate decline when the underlying paradigm has already shifted.

The current reset, Lin argues, is AI challenging the SaaS default.

The companies that survive these shifts — Netflix (DVDs → streaming → originals), Microsoft (cloud + AI under Nadella) — don't wait for confirmation. They interrogate their assumptions early, while they still have room to act.

"Peter Drucker once observed that no matter how obvious they appear, we must always question all assumptions (defaults), because in a surprisingly high percentage of cases, what is known to be true turns out to be only partially true, inaccurate, or simply the residue of a world that no longer exists. What was a feature yesterday is merely a default today and may become a bug tomorrow."
