Social Network

Occhio non vede, Social Network te lo dice

Viviamo in una società in cui anche l’ impossibile diventa possibile. Ebbene si,per quanto assurdo possa sembrare,al giorno d’ oggi, basta accedere un pc per essere aggiornati riguardo la vita di altre persone che vivono lontane da noi, il tutto grazie ai social network,i quali come tutte le cose,posseggono lati positivi e negativi che sembrano emergere sempre più. Da recenti studi,infatti si evince che l’ uso frequente dei social comporti non pochi problemi o addirittura dipendenze paragonabili a quelle da alcol o droga. Non è facile diagnosticare ad una persona un disturbo causato dal frequente utilizzo dei social,perché non vi sono sintomi i quali permettono di riconoscerlo, ma lo si può evincere. Basta osservare quanta poca importanza si conferisca al relazionarsi con gli altri. Basta pensare si preferisca parlare con una persona separati da uno schermo e non davanti ad un buon caffè,guardandosi negli occhi. E quando ci si ritrova l’ uno accanto all’ altro,cosa accade? Nulla. Il silenzio finisce per essere il protagonista,perché non si ha niente da dirsi,il social ha già rivelato più del dovuto. È evidente che questi ultimi abbiano reso la società in cui viviamo definibile “società dell’occhio non vede,social te lo dice. O forse,sarebbe meglio dire,l’ abbiano resa “social dipendente”. Infatti,si sente il bisogno di condividere con il mondo ogni istante della vita,come se ciò servisse a far sentire forti e a far nascondere le debolezze,violando la privacy. La dipendenza da social network è diventata una vera e propria emergenza alla quale far fronte. Occorre far comprendere,soprattutto agli adolescenti,che i social siano un qualcosa di positivo solo se utilizzati correttamente,ossia evitando di condividervi vari aspetti di vita quotidiana e conferendo più spazio alle chiacchierate guardando l’ altra persona negli occhi,perché questa è la vita vera,queste sono le vere relazioni.

Valori

Recuperiamo i valori perduti

Combattere per i propri ideali, per trasmettere i propri valori, anche a costo di lasciarci la pelle.

Questo facevano i giovani del passato. E adesso, cosa resta di quel passato? Nulla, tranne l’ amaro in bocca causato dai ricordi e dalla consapevolezza del fatto che purtroppo le cose siano cambiate. In peggio, per alcuni versi. Viviamo in una società in cui si conferisce più importanza all’ apparire che all’essere. In cui non c’è spazio per chiunque non possieda un cellulare all’ ultimo grido o non indossi capi griffati. Come se l’ abito facesse il monaco! Ebbene si, per quanto brutto possa sembrare, quella odierna è una società che si dispera se si rompe un cellulare, che si innamora tramite un social network e, quando ci si vede tra amici, non si parla. Ciò, indica che valori come amicizia, amore e famiglia siano ormai scomparsi, soprattutto tra i giovani. Tutto questo non è tollerabile, occorre recuperare questi valori. È necessario che i giovani ricomprendano il senso della riservatezza, smettendo di condividere ogni attimo della propria vita, perché questo non significa vivere realmente.

Vivere realmente significa cadere sette volte e rialzarsi otto, significa sacrificarsi pur di raggiungere un traguardo e innamorarsi dopo aver guardato una persona negli occhi, apprezzandola per come è, non per come appare. La vita è il dono più prezioso che si possieda, perciò recuperiamone il senso. Ciò non significa di certo non favorire il progresso o la tecnologia, significa saper equilibrare le cose, ritagliando del tempo per spegnere i cellulari ed accendere i cuori, proprio come un tempo.

Clonazione della mente umana

Cosa succederebbe se clonassero il tuo cervello in un chip?

Molti tra i più famosi scienziati ritengono che nei prossimi decenni saremo in grado di clonare il cervello umano su un chip. Breve viaggio fra scienza, futuro e filosofia.

Il cervello umano è la macchina, di cui conosciamo l’esistenza, più complessa nell’universo: 86 miliardi di cellule chiamate neuroni interconnesse fra loro che si scambiano segnali chimici durante tutta la vita di un essere umano. Questo complesso sistema di cellule, di cui conosciamo ben poco fino ad oggi, costituisce la rete neurale che ci permette di compiere ogni azione della nostra vita, dal parlare al sognare.

Le capacità di una mente umana sono straordinarie e neanche i più potenti computer del mondo si sono mai avvicinati alle peculiarità dell’organo dove risiedono la nostra coscienza, la nostra memoria e i nostri sentimenti. Molti pensano che tutto questo sia dovuto solo a processi puramente fisici e chimici, altri credono che la coscienza e la vita in sé siano proprietà emergenti che non si possono spiegare solo a livello meccanico; forse la clonazione del cervello umano potrebbe dare una risposta a queste visioni opposte, vediamo perché.

[quote pull=”center” author=”Christof Koch e Giulio Tononi nella rivista IEEE Spectrum” link=”http://ieeexplore.ieee.org/document/4531463/?arnumber=4531463″]La coscienza è parte del mondo naturale. Essa dipende, crediamo, solo dalla matematica e dalla logica e dalle non del tutto conosciute leggi della fisica, della chimica e della biologia; essa non nasce da una qualità magica o ultraterrena.[/quote]

Progresso tecnologico e Legge di Moore permettendo (fai click sul link per saperne di più), fra qualche decennio saremo in grado di fare sostanzialmente due cose:

Neuroimaging

  1. Mappare tutte le interconnessioni neurali durante le funzioni dell’attività cerebrale, utilizzando avanzate tecniche di neuroimaging già esistenti, come la risonanza magnetica funzionale;
  2. Sviluppare tecnologie elettroniche e informatiche abbastanza potenti per l’esecuzione di una mente umana caricata su un supporto tecnologico.

Questo ci permetterebbe da una parte di conoscere tutti i “collegamenti” che costituiscono il nostro cervello anche non capendone il funzionamento, e dall’altra di caricare queste connessioni, conosciuto come mind uploading, così come sono in una realtà simulata al computer e osservare cosa accade. Il principio è il medesimo per cui scegliendo un sistema complesso a piacere, se sono in grado di copiare fedelmente ogni singola connessione, riesco a produrre una copia funzionate pur non conoscendo la logica del suo funzionamento.

[quote]La copia della mente su un supporto digitale potrebbe garantire l’immortalità all’umanità[/quote]

Questo piccolo “esperimento” potrebbe portare a una vera e propria rivoluzione non solo in campo scientifico ma anche filosofico! Proviamo a immaginarci cosa potrebbe accadere:

 

  • Primo caso: la copia non funziona. Da alcuni questo potrebbe essere considerato la dimostrazione che la mente umana e tutto quello che ne deriva (coscienza, sentimenti, memoria, creatività ecc.) non siano solo frutto di processi fisico-chimici, ma anche di realtà metafisiche che noi oggi chiamiamo anima; quel soffio vitale che ci distingue da ogni macchina che potremmo mai inventare.
  • Secondo caso: la copia funziona. Questo caso, al contrario, potrebbe essere la conferma “sperimentale” che le nostre capacità, anche quelle più complesse, siano date da altrettante complesse relazioni fisiche che si verificano nell’organo cervello. Se da una parte questo caso sembrerebbe darci delle certezze in più, dall’altra aprirebbe questioni ancora più difficili e a tratti inquietanti; infatti si verrebbe a creare un curioso paradosso: come potrebbe l’individualità di una persona esistere in due realtà differenti? La copia caricata su un computer può essere considerata identica all’originale, o verrebbero copiati solo i ricordi e la personalità dell’individuo fino a quel momento? Risposte difficili anche solo da pensare, che già da oggi scatenano non pochi dibattiti a livello etico, politico e filosofico.
Mind uploading
Tratto dal film “Io, robot”

Forse l’aspetto più intrigante di tutta la questione è che trasferire la mente da un “supporto biologico” a un supporto digitale potrebbe assicurarci l’immortalità! Sia ben chiaro, per ora parliamo solo di fantascienza, ma le premesse tecnologiche ci sono e forse fra qualche anno potrebbe diventare una realtà, voi non siete curiosi di scoprirlo?
