Kun työkalut rikkovat itsensä, järjestelmän pitäisi muistaa, miksi, eikä koskaan toistaa virhettä
Milloin *DiSE Hän tekee murhan.
> **Huomaa:** Tämä on spekulatiivinen suunnitelma DISE:n seuraavalle evoluutiohypylle – itseään parantavalle työkaluekosysteemille, joka seuraa sukupuuttoa, havaitsee vikoja, karsii epäonnistuneita oksia ja oppii virheistä ikuisesti. Se on kunnianhimoinen, hieman pelottava, ja se saattaa itse asiassa olla toteutettavissa jo olemassa olevan kanssa.
Tässä skenaario, joka pitää minut hereillä öisin:
Tool: data_validator_v2.3.0
Status: Working perfectly ✓
Evolution triggered: "Optimize for speed"
↓
Tool: data_validator_v2.4.0
Status: 40% faster! ✓
Side effect: Now accepts invalid emails ✗
Applications using v2.4.0: 47
Bugs introduced: 47
Developer frustration: ∞
Nykyinen DISE-järjestelmä voi kehittää työkaluja paremmiksi, mutta mitä tapahtuu, kun evoluutio tekee niistä parempia pahempaaEntä jos optimointi tuo kriittisen vian? Entä jos työkalumutaatio rikkoo tuotantojärjestelmiä?
Tällä hetkellä havaitsemme epäonnistumisen, ehkä pahennumme, ehkä korjaamme sen manuaalisesti.
Mutta meillä ei ole opi siitä syvällä, rakenteellisella tavalla.
Me emme:
Pohjimmiltaan emme luo rokotetta, johon liittyy tunnistusjärjestelmä ja korjaustutkimusta, mutta DiSE antaa meille mahdollisuuden tehdä sen lähes vähäpätöisesti.
Se muuttuu tänään.
Käsitteellisesti näin se on suunniteltu. voisi treeniä.
Ajattele jokaista DISE-työkalua solmuna Gitin kaltaisessa suorassa Asyklisessä kaaviossa (DAG):

Ollaan rehellisiä siitä, mikä on todellista ja kunnianhimoista:
Jos tämä järjestelmä toteutetaan täysimääräisesti, se aiheuttaa jotain huolestuttavaa:
Työkalut, jotka muistavat jokaisen koskaan tehdyn virheen ja varmistavat, etteivät ne koskaan toista sitä.
Ei vain yksittäin. Kollektiivisesti.
Vika yhdessä työkalussa lisää tietoa jokaiseen vastaavaan työkaluun. Turvallisuushaavoittuvuus, joka löytyy mistä tahansa, on maailmanlaajuinen rajoitus kaikkialla.
Järjestelmä kehittää institutionaalista muistia.
Juttu on näin: Institutionaaliset muistiyhdistelmät eksponentiaalisesti.
Kutakin sukupolvea rajoittavat kaikki aiemmat virheet.
Tämä on joko:
Jos todella rakennamme tämän, tässä on käsky:
Yhteensä: ~9 viikkoa keskittynyttä kehitystä
Itseparantuminen sukupuuttoon tietoisen karsimisen kautta ei ole vain ominaisuus, vaan perustavanlaatuinen muutos siinä, miten ajattelemme koodin sukupolvesta.
Perinteiset järjestelmät:
Generate → Test → Use → Fail → Regenerate → Repeat forever
Itseparannusjärjestelmät:
Generate → Test → Use → Fail → Learn → Prevent → Heal → Never repeat
Erona on muisti.
Ei vain muisto siitä, mikä toimi. Muisti siitä, mikä epäonnistui ja miksi.
Ja tämä muisti leviää jälkeläisten kautta, samanlaisten työkalujen kautta, koko ekosysteemin kautta.
Järjestelmä kehittää vasta-aineita.
Kun vika havaitaan, se ei voi toistua siinä muodossa. Malli muistetaan, välttelysääntö luodaan, tieto leviää.
Näin immuunijärjestelmä toimii.
Näin järjestöt oppivat.
Näin sivilisaatiot kehittyvät.
Ja nyt koodi voi kehittyä näin.
Tämä on tällä hetkellä suunnitteluasiakirja, ei työominaisuus, mutta jos haluat auttaa sen rakentamisessa:
Tavoitteena ei ole rakentaa täydellistä järjestelmää ensimmäisenä päivänä.
Tavoitteena on rakentaa järjestelmä, joka voi ota oppia jokaisesta virheestä sekä älä koskaan toista sitä.
Jos pystymme siihen, olemme luoneet jotain aidosti uutta.
Ei vain parempaa koodisukupolvea.
Koodi, joka muistaa.

Sarjanavigointi:
Tämä on suunnitteluasiakirja DISE:n itsensä parantamiseen. Keskeisiä mekanismeja (linjaus, evoluutio, RAG-muisti, testaus) on jo olemassa. Tässä artikkelissa kuvataan, miten ne yhdistetään järjestelmään, jossa työkalut oppivat epäonnistumisista eivätkä koskaan toista virheitä. Se on kunnianhimoinen. Se voi olla toteutettavissa. Ja jos se toimii, se muuttaa kaiken siitä, miten koodi kehittyy.
Epämiellyttävä rinnastus: Näin immuunijärjestelmä toimii. Näin järjestöt oppivat. Jos koodi pystyy tekemään tämän mittakaavassa, mikä muu käy mahdolliseksi?
