On scial media，many Chinese nted that the AI presenters did nt seem real.Peple blamed them fr nt being mre lifelike.Others wndered abut the effects rbts might have n emplyment and wrkers.Sme peple argued that nly lw-level jbs requiring heavy labr will be easily replaced by rbts.Others praised the technlgy as a way fr cmpanies t make mney frm lw-cst labr machines.Sme businesses have experimented with similar technlgy fr pssible use in news peratins.Britain’s BBC recently released a vide that used machine learning t make it lk like ne f its news readers speaking different languages.The Lndn-based cmpany that develped the system says its gal is t “remve the language barrier” fr many different kinds f vide acrss the Internet.
