document.all. There were new frameworks coming out everyday and every job was requiring years of experience with each one. I had to learn them all if I wanted to make a living writing code.
What I didn't know at the time was that the software world has always been like that. In fact there was an advantage to being the last person to pick up the book. You couldn't possibly learn everything, and most things become irrelevant quick enough. Remember Silverlight?
By the time I started learning about AI, all the resources were already available. Any time something was obscure to me, someone had already gone through the same issue. They had the time to write a detailed blog post with interactive figures that helped me better understand. When I followed videos on YouTube, the entire class that had been uploaded over the course of two years was available to me. I could watch it everyday rather than wait for a week or two for the next installment.
I went on to complete programs from Deeplearning.ai in a month instead of the 3 to 4 month recommended. The last person to start gets to learn from the pitfalls of those who paved the way. They don't have to spend the time working on tech that was only a fad. I'm the last person to learn, but I won't be too far behind in knowledge.
