> Working for a public institution
This may vary from country to country, but in my part of the world, public institutions are mostly dysfunctional, political, nepotistic, filled with cronies and people with negative productivity. And then there's one bright eyed idealist who actually does most of the work until they realize they're being taken advantage of, learn their lesson and starts behaving the same (or leave for private sector).
> Joining a tech co-operative
ie. become a freelancer or start/join a consultancy; sure, but after a couple dozen projects, it starts feeling the same as a corpo job.
> Joining a tech NGO
Again, may vary from country to country. Here NGOs are incredibly political things and desperately dependent on continous outside funding (the two are interconnected). You'll switch office politics for NGO politics.
> Working for a union or a party
Politicians and union representatives are some of the last people I'd ever want to socialize with.
> Becoming a mentor or a teacher
That's nice, but can you live on that salary?
> Becoming a techno-political hustler
For an article that starts with one's quest to find a more meaningful job, this is about as far removed from it as "used car salesman that exclusively uses bitcoin payday loans financing".
At the same time, some of the more promising alternatives that crop up at local IT watering holes are floor tiling, plumbing, roofing, ... All honest work, good pay, visible results, and zero bullshit.
