Thank you for your interesting talk! It probably depends on the audience, but for me personally the level could have been a bit higher. Most people nowadays probably know how Composer works and that it makes autoloading a breeze compared to 'ye olde days'. Other than that, I really liked you showing how there is a whole world between using a full-blown framework and building everything from scratch.
PS: Small bug in the slides: In the HTML form for the 'Handling Configuration' part, the `type` attributes on the elements should probably be `name`, and a `name` is missing on the .
The idea of the talk is nice! But after 'installing' two packages you know where the talk goes to. Maybe it's more like; I've been there before, so maybe I was not the right audience? For (younger?) people without the experience of building an framework from scratch, it's an great way to learn more about "behind the framework scene".
If you are working with frameworks a lot you'd lose sight about what is happening under the hood. This talk gives great insigth what simpel things are happening in a framework. The components/libraries can be complex but the idea of constructing a framework with components/libraries simply from packagist is awesome.
