just to be clear: from my standpoint it's the worst period ever being a junior in tech, you are not "fucked" if you are junior, but hard times are ahead of you.
This case has always been made for juniors but it's almost always the opposite that's true. There's always some fad that the industry is over-indexing on. Senior developers tend to be less susceptible to falling for it but non-technical staff and junior developers are not
Whether its a hotlang, LLMs, or some new framework. Juniors like to dive right in because the promise of getting a competitive edge against people much more experienced than you is too tantalizing. You really want it to be true
Some things take very little time and effort to manifest into the world today that used to take a great deal. So one of the big changes is around whether some things are worth doing at all.
Note: I'm not taking any particular side of the "Juniors are F**d" vs "no they're not" argument.
