There are a lot of really nice frameworks, like elixir with nerves, which make iot development a breeze. I'm sure it's not a pancea, but it's easier than coding in C or something like that for your firmware. With nerves, you can write your backend and firmware in the same language (elixir) and you don't need to worry too much about embedded things like memory insufficiency since nerves handles it all. I'm sure there are cases where you have to use a low level language, but those will decrease over time as hardware gets better and more efficient.
