> Juniors need to leap into their careers and build up a good head of steam by demonstrating acquired experience,

Junior devs at least have the option of building a portfolio of usefully software on their own machine at home, while eating ramens.

They can build websites for mom'n'pop stores. They can participate into open source projects. Etc, etc...

I dread the people who won't get jobs into other fields because managers have been told by corporate that "we don't need people, chatgpt can do everything".

For many, even cutting their budget isn’t enough to pursue what you’re describing. Modern careers in software are very hard to reach for people who can’t afford to wait for a real paycheck, and it drives away a massive group of potential talent.
