Someyearsago,whentheGoogleBooksproject,whichaimstodigitisealloftheworld’sprintedbooks,wasgettingunderway,thetwoco-foundersofGooglewerehavingameetingwiththelibrarianofoneoftheuniversitiesthathadsignedupfortheplan.Atonepointintheconversation,theGoogleboysnoticedthattheircollaboratorhadsuddenlygoneratherquiet.Oneofthemaskedhimwhatwasthematter.“Well”,hereplied,“I’mwonderingwhathappenstoallthisstuffwhenGooglenolongerexists.”Recountingtheconversationtomelater,hesaid:
“I’veneverseentwoyoungpeoplelookingsostunned(震惊的):
theideathatGooglemightnotexistonedayhadnevercrossedtheirminds.”
Andyet,ofcourse,thelibrarianwasright.Hehadtothinkaboutthenext400years.Butthenumberofcommercialcompaniesthataremorethanacenturyoldisvanishinglysmall.Entrustingtheworld’sliteraryheritagetosuchtransient(短暂的)organisationsmightnotbeentirelywise.
Comparedwithmylibrarianfriend,wehavetheattentionspanofnewts.Weareconstantlyoverawed(使敬畏)bythesize,wealthanddominanceofwhateverhappenstobethecurrentcorporategiant.Atthemoment,thefourleadingmonstersareApple,Google,FacebookandAmazon.Yet18yearsago,Applewasweeksawayfromextinction,Amazonhadjustlaunched,GooglewasstillthreeyearsawayfromincorporationandFacebooklaynineyearsintothefuture.
Atonelevel,allthisprovesisthatinthetechnologyworldonecangofromzerotoheroisaveryshorttime.(Or,inApple’scase,fromherotozeroandbacktoheroagainin36years).Someoftheindustry’sgreatestexecutivesunderstoodthisverywell.AndyGrove,forinstance,wholedIntelfor11years,wasfamousforhismantra“Onlytheparanoidsurvive”.Formanyyears—whenheledMicrosoftandbeforeheembarkedonsavingtheworld—BillGatesappearedtohavethesamesentimenttattooedonhisforehead.Andinbothcasestheyturnedouttoberight:

Weunderstandprettywellthefactorsthatdeterminethefortunesofcompaniesthatmakethingspeoplebuy—whichiswhy,forexample,onecanpredictthatApplewon’tbeableindefinitelytosustainitshugeprofitmarginsonitsiDevices.Likewise,it’sprettyeasytopredictwhereAmazonisheaded:

ThisleavesFacebook,acompanythathasonebillionproducts(calledusers)andearnsitslivingbysellinginformationaboutthemtoadvertisers.GiventhatholdersofFacebookaccountsdon’tpayfortheservice—andarethereforefreetodepartatanypoint—you’dhavethoughtthatitslong-termdurabilitywouldbequestionable.Andyetlotsofinformedandcanny(精明的)investorsdisagree.Theyappeartoregardthecompanyasasure-firebet.
ThetwokeyfactorsthatwilldetermineFacebook’sfuturearethepowerofnetworkeffectsandthe“stickiness”ofitsservice—ie,theextenttowhichitcandissuadeusersfromleaving.Anetworkeffectcomesintoplaywhenthevalueofaproductorserviceisdependentonthenumberofpeopleusingit.Atelephonenetworkwithamillionsubscribersisinfinitelymorevaluablethenonewithonly10.Intechnologicalecosystems,networkeffectsareverypowerful:
