There may be a small bit of truth in each claim, but they are mostly false.
> LLMs and Agents are not automating SWE, but they are changing it.
LLMs are maybe a slightly larger threat to SWE careers than the ability to copy/paste code from stack overflow.
> Interviews have become nightmares
Interviews if anything have gotten slightly better. Companies stopped asking riddles like, “how many windows are in Seattle”.
> A lot of SWE work is objectively make-work, and a lot of startups are building fluff or things that are net negative to society.
This has been the case for a long long time.
> Beyond this, the supply for SWEs vs the demand is clearly imbalanced on the supply side.
Tech salaries say otherwise. They don’t pay 3-4x the average household income out of kindness.
> Is SWE a sustainable career anymore?
Definitely, though it depends on your definition of sustainable.
If you want a remote position, 30 hour work week, and a $200k+ salary maybe not.
But lots of people will continue to earn a good amount in an overall cushy job as SWEs for the foreseeable future.
