Software is the hardest thing on planet earth. That's why there's this concept of bootcamps. No other profession has this concept of "bootcamps".
Building a plane is easier than building software. That's why they don't have bootcamps for building planes or becoming a rocket engineer. Building rockets or planes as an engineer is a breeze so there's no point in making a bootcamp.
That's the awesome thing about being a swe, it's so hard that it's beyond getting a university degree, beyond requiring higher math to learn. Basically the only way to digest the concept of software is to look at these "tutorials" on the internet or have AI vibe code the whole thing (which shows how incredibly hard it is, just ask chatGPT).
My friend became a rocket engineer and he had to learn calculus, physics and all that easy stuff which university just transferred into his brain in a snap. He didn't have to go through an internet tutorial or bootcamp.
