 N\u011bkte\u0159\u00ed tvrd\u00ed, \u017ee jde o po\u010d\u00edta\u010dovou apokalypsu. N\u011bkte\u0159\u00ed celou kauzu bagatelizuj\u00ed. Kde je pravda? Ta se bude jen t\u011b\u017eko hledat. Fakt je, \u017ee Intel hodn\u011b zav\u00e1hal, alespo\u0148 tedy v informovanosti.
 
 Nejprve toti\u017e o chyb\u00e1ch neinformoval nikoho. Pr\u00fd proto, aby toho nemohli vyu\u017e\u00edt po\u010d\u00edta\u010dov\u00ed pir\u00e1ti. No budi\u017e. Dejme tomu. Ale pro\u010d pot\u00e9 byla informov\u00e1na nejprve \u010c\u00edna, pak USA a teprve potom zbytek sv\u011bta?
 
 
 P\u0159itom jsou ob\u011b chyby, Meltdown a Spectre opravdu kritick\u00e9. A to hodn\u011b. Lze je toti\u017e vyu\u017e\u00edt tak, \u017ee v\u00e1m bude vir vpa\u0161ov\u00e1n p\u0159\u00edmo do procesoru a proti tomu zat\u00edm neexistuje v\u016fbec \u017e\u00e1dn\u00e1 obrana. S adresn\u00edmi prostory toti\u017e neum\u00ed pracovat \u017e\u00e1dn\u00fd antivirov\u00fd program na sv\u011bt\u011b. Neum\u00ed je prohledat. A v tom je velik\u00e1nsk\u00fd probl\u00e9m.
 
 V z\u00e1jmu pravdy je v\u0161ak t\u0159eba napsat, \u017ee prvn\u00ed v\u00fd\u0161e jmenovan\u00fd je skute\u010dn\u011b jen a jen z\u00e1le\u017eitost\u00ed Intelu, druh\u00fd je z\u00e1le\u017eitost\u00ed n\u011bkolika modern\u00edch procesor\u016f. A tak\u00e9 nutno dodat, \u017ee Intel ji\u017e musel \u0159e\u0161it mnohem slo\u017eit\u011bj\u0161\u00ed z\u00e1le\u017eitost kolem probl\u00e9mu nazvan\u00e9m Pentium F00F bug z roku 1997. Ten byl mnohem v\u011bt\u0161\u00ed pohromou ne\u017e dne\u0161n\u00ed Meltdown. Nav\u00edc tato slabina by nem\u011bla dovolit proniknut\u00ed vet\u0159elce do chr\u00e1n\u011bn\u00e9 pam\u011bti. Nu, nem\u011bla by.
 
 
 J\u00e1 se domn\u00edv\u00e1m, \u017ee je to op\u011bt popisov\u00e1n\u00ed z\u00e1niku sv\u011bta bez n\u011bjak\u00e9ho zvl\u00e1\u0161tn\u00edho d\u016fvodu. Intel m\u00e1 dost chytr\u00fdch lid\u00ed, aby se s chybou (chybami) vypo\u0159\u00e1dal v\u00edce ne\u017e d\u016fstojn\u011b. \u00dadajn\u00e9 zpomalen\u00ed stroj\u016f, kde se hovo\u0159\u00ed a\u017e o pades\u00e1ti procentech se tu\u0161\u00edm zat\u00edm nekon\u00e1, a pravd\u011bpodobn\u011b ani konat nebude. P\u0159esto je pot\u0159eba v\u011bnovat probl\u00e9mu dostatek pozornosti, a hlavn\u011b ud\u011blat n\u011bco jako premedikaci. Toti\u017e za\u0159\u00eddit to tak, aby se podobn\u00e9 chyby neopakovaly. 
 
 Na obranu Intelu mo\u017eno snad napsat to, \u017ee chyby byly objeveny ned\u00e1vno a \u017ee se ihned zkou\u0161\u00ed jejich opravy. To, \u017ee Intel jako takov\u00fd, sv\u011bt neinformoval mu ov\u0161em nikdo nezapomene. Ale ruku na srdce, kdyby ona informace pronikla mezi ve\u0159ejnost, kdyby ji Intel sv\u011btu sd\u011blil, neprovedl by t\u00edm medv\u011bd\u00ed slu\u017ebu? Co mysl\u00edte?
