不久前，猎豹移动董事长兼CEO傅盛在一次访谈中谈到，机器人创业之所以火，第一是因为好融钱，第二是因为这件事并不难。据他描述，在深圳成熟的供应链体系下，投入200万元，就能定制一款具备基础行走功能的人形机器人样机，贴上自有品牌logo，就能对外宣称布局人形机器人赛道，进而包装PPT对接资本融资。

Why Raising VC Too Early Is the Fastest Way to Kill Your Startup
25Carboxysome is especially illuminating as it offers another instance of convergent evolution; the two lineages of carboxysomes (α and β) in marine and freshwater cyanobacteria evolved independently but share the same general structure, despite differences in gene organization and protein sequences. Only 100-500 nm in diameter, these icosahedral structures are composed of hexameric proteins, with pentamers at the vertices. They serve as reaction chambers for ribulose bisphosphate carboxylase/oxygenase (RuBisCO), the famous CO2-fixing enzyme, known for its catalytic slowness and poor selectivity for CO2 over O2. Inside carboxysomes, RuBisCO is colocalized with another enzyme, carbonic anhydrase, which converts bicarbonate into carbon dioxide. Thanks to the local abundance of CO2, RuBisCO is much more efficient than on its own. Carboxysome shells are also selectively permeable for oxygen, mostly keeping it out and preventing it from competing with CO2 for RuBisCO’s catalytic activity.
