You're basically describing my work day. My job went from interesting, highly skilled work to mostly horrible brain rot over the past year.
It's depressing and I don't know a way out. Other then a complete career change, throwing away 30 years of experience and a matching salary.
I only have 10 years of experience, so I'm not trying to say that your lived experience is invalid, but personally I figure if this is the way the industry is heading then I may as well try to learn how to thrive within the new environment.
The current hype cycle might even represent a net global gain like some people argue. But it represents yet more externality driven exploitation. Remains to be seen what the new equilibrium will be given that now the population being exploited is not only close to the core of the world system but also already overburdened.
I do think it represents a mere acceleration of the previous trend that resulted since around 2005 in an explosion of average (not median) pay for software developers due to similar dynamics. If the system settles on a new level of pay that manages to convince enough people of enough skill to go along, it might just hum along and not implode. As for the rest of us, welcome to the growing permanent underclass and brace for the impact of the climate wars. We will be the fodder that will insulate the chosen ones under their air conditioned domes.
If you’re unhappy, make a change.
The real question isn't if things are going to change around our jobs, its are we going to be able to move fast enough to avoid starving in the streets?
