Working my way up to build a AI Model from scratch

Yeah. If your goal is to use or contribute to the AI ecosystem, that’s probably a safe bet. It’s reasonable to assume that building an AI model from scratch—one that has reached the latest practical level—requires the capital and resources of a massive startup or a global corporation. It’s more of a sophisticated industrial product than a work of art created by a single artisan. Alternatively, if AI itself isn’t part of your objective, you could simply choose not to participate in the AI ecosystem at all. You could focus on something completely unrelated, for example.
