I think its like with every thing else; when things change its often for the better but there are always aspects you can look at that seem compromised, and its then easy to throw the baby out with the bath water.
calculators are a good example - I agree with many others that the modern mindset is less able to error check as its all just punched in, but give somebody 1000 sums to do manually vs 1000 with a calculator and there will be less errors overall with the calculator. So in a way you just accept the new methods as sometimes creating these type of silly errors, because overall it outperforms the alternative
satnav is another good example - the modern mindset may not be able to find their way from A to B with just a map book, and they may be more prone to punching in a postcode incorrectly and not spotting the error before its too late... however, I bet when you take the bigger view that they get lost maybe 1 in 1000 times vs how often do you think motorists got lost 50 years ago? 1 in 3?
On the topic of there being more mental health issues around now, I really don't know about that as I don't have the data, but I'm pretty certain that its being recognised / declared / dealt with a hell of a lot more nowadays, which I am pretty sure is skewing people's perspective on how commonplace it is vs how commonplace it was.
same with neurodiversity - my eldest daughter was diagnosed with asperges 2 years ago, my youngest has ADHD.... and then having gone through the process with them both, I realised I had something going on too! I was diagnosed just a year ago, and I'm 47
I think the UK is much like the original topic of this thread - lots of change, some of it bad, but overall working really well for most people. And I'm saying that having just gone through (and still going though) the toughest 2 years of my life. And its nothing to do with Covid....
