The more AI generated slop invades social networks, the more valuable real genuine content feels to me. I donโt think generated content is the future at all. I donโt think people want to follow a bot, and that is how it feels.

Another Compose + AGSL warping shader example ๐คฉ
You can do cool things with shaders in Compose using RuntimeShader and AGSL (Android Graphics Shading Language). Here is a warping effect shader ๐ตโ๐ซ This code runs directly on the GPU using Android's RenderEngine.

Strong skipping has been enabled by default for a while in Compose, yet official docs still say things like unstable params make Composables not skippable. Very confusing if you ask me, especially for people starting with Compose. https://t.co/FlqKln1jgE

When people see some crazy good piece of art on the internet, they immediately say itโs AI. When someone loses a big amount of weight in short time, then itโs ozempic. I donโt think anyone believes in hard work or effort anymore. Soon nobody will put in the work or time things

Quantity is high for sure, but quality is obviously so low these days with AI. People releasing slop like crazy, in all forms. Care for user experience fading out at gigantic steps. What a great opportunity for software engineers to bring in their expertise.

AI clearly helps kickoff projects quick, but it still requires human touch when it comes to complex enough things. At least that was my experience with https://t.co/6OXE1RdAkF, especially with all the editor canvas stuff. Creating a well rounded product is hard.
