(and I'm not being "deliberately obtuse", although you are being highly patronising).
It's not patronising to point out that you
may have been being obtuse in needing it spelled out how technology has created efficiencies. I apologise for assuming that it was self evident.
almost all of these so called "efficiencies" you describe are just removing jobs from the economy, affecting exclusively working class people, not the middle classes.
Removing human labour, which requires a salary, sick leave, a pension, and sleep, whilst still having the work done and generating a profit is the dictionary definition of efficiency. The more tech advances, the further up the class system those replacements happen.
it will also eliminate a major number of taxi driver jobs that form a huge part of the service economy all over the world.
Again, achieving massive efficiencies within an economy, if the work being done doesn't require humans to do it.
why are you advocating for the replacement of humans by technology in multiple sectors?
I'm not advocating for it, I'm just saying it will happen. Pretend you are a filthy capitalist. Do you want to employ a human to do a good job 8 hours a day 5 days a week, ~40 weeks a year, or a robot to do a sufficient job potentially 24/7?
I work as a copywriter for brands and I don't believe chat gpt will make my job redundant per se, but it is very much a potential nuisance and people thinking AI can write good copy (it can't yet) serves to undermine the perceived value of what I do and what I've spent the best part of a decade working to be brilliant at.
Once AI becomes good enough, then your job will be replaced in most workplaces. Some organisations will probably continue employing real people to do these jobs, but they'll get rarer and competition for them will be fiercer.
all that these technologies will do is create increasingly fewer jobs for those who need them the most.
Exactly. That's why fundamental reform of the economic systems is required, rather than tinkering around the edges, as I said before.
I see little to no correlation with or relevance to the pension age
Well, in capitalistic systems, efficiency means more profit by reducing the amount of work (cost) to create the same product/output. The current economic model mean that efficiency means the assumption that the workforce will do more, in turn creating even more profit. As such, people still work the same hours until the same age or later
This is a choice, and is one of the drivers of the increasing wealth gap globally and within many countries. As an over simplistic example, if a job that once took 10 hours a week now takes 8 hours, then that 20% efficiency saving could be passed on to the worker by reducing their work week, or be absorbed by taxes to allow for a larger pension fund. This would then allow retirement age to stay the same or even be lowered.
It is economically conservative to just choose to continue working a 35 to 40 hour week, retire later, and use efficiencies to increase profits and lower the rate of tax on business to maintain the current functions of the state. He'll, it's economically conservative to argue that everyone NEEDS to have a job at all.
A more redistributive economic model could radically change the amount of labour people would need to do across the economy, by spreading those benefits more equally, rather than having them primarily benefiting already wealthy shareholders.
In the immediate term, Macron could choose to raise corporation tax, or create a new wealth tax, and that would fund pensions without having to require people work longer so that money comes from income tax instead.
Longer term, these issues will need to be looked at as more and more human labour is replaced, and we're reaching a point where machines and technology can begin to replicate human behaviour, decision-making, and creativity. Whacking up the pension age isn't going to come close to solving the issues that brings.
