### Entreprise lifecycle
> Il existe depuis longtemps un cycle de vie pour les entreprises : les jeunes entreprises innovent, sont avides de cash et se cherchent désespérément des financements. Certaines y parviennent, vendent leurs produits et se retrouvent à gagner plus d'argent qu'elles n'en ont besoin. Les grandes entreprises prennent cet argent et l'investissent dans des produits encore meilleurs, emmenant l'entreprise vers de nouveaux sommets. \[...]
>
> Mais, inévitablement, les technologies des entreprises deviennent standardisées et banalisées. De nouvelles technologies, plus brûlantes, prennent leur place, et l'entreprise n'attire plus les meilleurs travailleurs, parce que, justement, elle ne représente plus la prochaine chose à la mode. Les nouveaux produits connaissent une perte de vitesse, les vieux produits ne sont plus aussi rentables que par le passé (car les concurrents comprennent comment faire quelque chose de mieux), et les marchés et les consommateurs passent à autre chose.

### Fullstack Developper
Aka Full stack or full-stack developper
Being able to do it all vs being able to be talented in all is a huge difference. It's not related to language, frameworks or tools, but concepts like performances, security, accessibility, ergonomy / UX, efficiency (multiple ways to do the same thing, but with diff. impacts), load balancing, design, etc.
It's like a One-man band, can't easily play a Symphony or even not at all.
More a lego player/builder than a brick craftsman/manufacturer
Fullstack dev can create a prototype, but not a large scale project solo
Full stack = for prototypes, MVP, only one dev; frontend, backend, devops Not for team or at least without expertise requirements
> Full stack devs originate from startups where you have to get your hands dirty in all the fields if you want to succeed, but as soon as you're able, you have to hire specialists if you want to have your product follow the highest security, efficiency and design standards, packed in a good, presentable but not bloated UI.
> A full stack developer is “A developer who can introduce a bug to every layer of the software stack.”
