Backpropagation is a leaky abstraction (2016)

Given that we're now in the year 2025 and AI has become ubiquitous, I'd be curious to estimate what percentage of developers now actually understand backprop.

It's a bit snarky of me, but whenever I see some web developer or product person with a strong opinion about AI and its future, I like to ask "but can you at least tell me how gradient descent works?"

I'd like to see a future where more developers have a basic understanding of ML even if they never go on to do much of it. I think we would all benefit from being a bit more ML-literate.

so if you want to have a strong opinion on electric cars you need to be able to explain how an electric engine works right?
