Command economies can make risky bets on particular technologies or strategies, and just reorganize everyone's life around this goal. It is very authoritarian, often tyrannical, but the notion that it is necessarily inefficient is just stupid. Planning occurs in markets too. A Boeing jet takes decades to bring it to market, and the organization must make risky long term plans and bets. They may pan out, or may not. But every entrepreneur and startup at YC is doing the same sort of thing. Taking losses for years, even, because of a belief in their plan. Sometimes, risky bets pay out. Sometimes spectacularly. And sometimes they crash and burn. The resilience of a market economy means that not everyone has to be on board for such a venture. Indeed, the market is a collection of organizations that are all either slowly or quickly in the process of failing. None of them will last forever, but they generally won't all fail at the same time. A command economy can, and often does.
