I think at least part of the reason tech has become complex is because so many tech stacks today are a briar patch of 3rd party libraries and components that no one person can understand. The 'Don't reinvent the wheel' rule of thumb has practically become a mantra, and enables this. Newer developers who grow up in the online community are so afraid to think for themselves, lest they get mortified to death for doing something dumb. So it's sort of a self-perpetuating complexity problem.
