Also EE here. Because in EE you need to invest a lot of funds into equipment, prototyping, manufacturing, RMA, shipping, logistics, customer support, etc. only to make pennies in profit when you actually sell your finished products, while it's the opposite for SW dev work, developing it and selling it costs you next to nothing, you just need a laptop and an internet connection, and once you sunk the cost of developing it you can scale it virtually infinitely and sell it across the globe with low costs and high margins.

Long story short, it's a lot more profitable to make apps where you get consumers to click on ads, buy stuff, or invest their savings into meme stocks or crypto, than to build and sell physical products to them (unless you're Apple).
