Sibonile ukuthi ukuguquguquka kwayo nokuzivumelanisa nezimo kuye kwayivumela kanjani ukuthi ibe yisisekelo sayo yonke into kusukela kuma-microcontrollers alula kuya kuma-supercomputer aphambili.

Izakhiwo ze-Von Neumann ziye zanqoba izinselelo eziningi phakathi neminyaka edlule, kusukela ebhodleleni elibizwa ngegama lakho kuya ekukhuleni kwezidingo zokusebenza nokusebenza kahle kwamandla. Kuzo zonke izinyathelo, onjiniyela nososayensi bathole izindlela ezintsha zokunqoba le mikhawulo, kungaba ngezinkumbulo zenqolobane, ukucubungula okufanayo, noma ukuhlanganiswa kwamayunithi akhethekile.

Uma ubheka phambili, kuyacaca ukuthi izakhiwo ze-von Neumann zizoqhubeka zidlala indima ebalulekile endaweni yezobuchwepheshe. Nakuba kuvela ama-paradigm amasha njenge-quantum ne-neuromorphic computing, cishe sizobona ukuhlanganiswa kwalezi zindlela nezimiso ezifakazelwe ze-von Neumann, kwakheka amasistimu ayingxube asizakala ngokungcono kakhulu kwemihlaba yomibili.

Ubani owaziyo ukuthi ikusasa liphetheni ngezinto ezintsha ezintsha? Mhlawumbe siseduze nenqubekela phambili entsha ye-quantum ekubhaleni , noma mhlawumbe inguquko enkulu elandelayo izovela ohlangothini olungalindelekile nhlobo. Okuqinisekile ukuthi ukwakheka kwe-von Neumann, kanye nokuzivumelanisa nezimo okumangalisayo, kuzohlala kuyingxenye ebalulekile yalelo kusasa.

Njengabasebenzisi bobuchwepheshe, kuyajabulisa ukucabanga ukuthi ngaso sonke isikhathi lapho sisebenzisa amadivayisi ethu, sixhumana nefa elisukela ekuqaleni kwenkathi yokwenza ikhompuyutha. Ngokuzayo uma usebenzisa i-smartphone yakho, usebenza kukhompuyutha yakho, noma usebenzisana nanoma iyiphi idivayisi yedijithali, thatha isikhashana ukwazisa ubunjiniyela obumangalisayo nokucabanga kombono okwenza kwenzeke.

Ukwakhiwa kukaVon Neumann akuyona nje umlando; kuyibhuloho phakathi kwesikhathi sethu sobuchwepheshe nekusasa lethu ledijithali . Kuyaqhubeka nokuba umthombo wokuphefumulela kwabasunguli kanye nobufakazi bamandla emibono eyisisekelo yokubumba umhlaba wethu.
