What it is

Deep learning is a subset of machine learning that uses layers upon layers of artificial neurons to process information. The "deep" bit just means there are lots of layers. It's the tech behind image recognition, voice assistants, and the reason your phone can identify your face even when you've just woken up looking like a haunted potato.

Why it matters for your job

Deep learning is what made the current AI boom possible. It's the engine underneath things like ChatGPT, image generators, and voice transcription tools. If you work with images, audio, video, or complex data, deep learning models are coming for the repetitive parts of your workflow. Some have already arrived.

What to do about it

You don't need to understand the maths. You need to understand what deep learning makes possible that wasn't before. Image classification, speech-to-text, language translation at near-human quality... these all run on deep learning. Figure out which of those capabilities overlap with your daily work.
