    Thank you for this explanation. It ‘clicked’ for me around 14:52 - realizing the infinite nature is because you can get infinitely closer to any point in the set without ever arriving to it - but it’s still a ‘real’ set of numbers that exhibit a geography based on stability. Awesome.

    In 1988, using a 386 based Windows PC, I built many Mandelbrot and Julia sets, one pixel at a time, and each image took a day or two to complete. Now, with processor speeds in the gigahertz and multicore processors working in parallel, each image takes milliseconds to complete. Was very interesting to watch the machine back then do the calculations and plot the pixels on the screen. Now, all the math is done in a flash. Shows how far we have come in technology. Still love the Mandelbrot images. They are seen everywhere in nature.

What data we have about it defines the past, and the predictability of the system’s effects defines the future. But really, time isn’t like this so your statement is simply wrong.

That said, there are plenty of jobs within that narrow field available. Plenty of schools ranging from beginning grade school all the way up to university need passionate mathemeticians to teach maths to their young students. Some professors make quite a lot of money studying their passion, and since passion is what drives both teaching and learning, that's the best career for anyone who loves maths.

However understanding vectors, matrices and quaternions is quite important if you do 3d graphics. In the game industry there are even other jobs like game design which is more about probability and balancing features. They usually toy around a lot with exponentials ^^.
      Though it depends on how deep you dive into certain topics. Procedural geometry or neural networks are also quite math heavy. Same goes for bezier curves or splines.

    You mentioned that you know a number is going to explode when the absolute value is greater than 2.
    I recently found out that the general formula for the best possible escape radius is 2^(1/(n-1)) where n is the power in the iterative formula. For the Mandelbrot set that's z -> z^2 + c so n=2 which indeed yields 2, but for other powers it's a different number.
