This comment made me want to ask this question.
What are some noticeable changes in the world or society or culture that you've seen growing up? Whether it be how people changed, how etiquette changed, how technology advanced, to music evolution, to fashion styles, etc. anything you want to mention. Bonus points if you share where you think it's going.
In the UK especially and after the end of WWII - some changes I've noticed, but mainly in technology or science:
The end of trams and trolley buses (some of the former brought back though); Change from valve radio to transistors (and further); First use of nuclear power for electricity generation and propulsion systems; The nature of DNA discovered; Development of the Hydrogen bomb; The development of psychopharmaceutical drugs; Widespread adoption of TV, and colour TV later; First satellites launched; Development of the integrated circuit; Greater adoption of car ownership; Change from steam to diesel trains (and then to electric); Fading out of steam locomotives altogether; Development of the hovercraft and the hydrofoil; Last common use of the horse and cart in the UK; First human in space; Full understanding of Plate Tectonics; Widespread adoption of audio recording technology; First man on the moon; Widespread use of credit cards (and then contactless); First supersonic passenger aeroplane in service; First VTOL aircraft; Advent of portable music players; First use of IVF; Widespread use of microwave ovens; First home computers; Widespread use of plane travel; Development and use of planetary probes, space vehicles, and space stations; First CD players, digital music, and video-taping technology; Development of DNA testing; Advent of digital photography; Development of the internet; Widespread use of GPS systems and associated mapping technology; First animal cloned; First transplants of human organs and limbs; Development of laptop computers and similar devices; Human genome mapped; Development of surround-sound systems; Further development of portable music players (digital); Widespread use of mobile phones; Widespread use of cashless payment systems; Widespread use of radio time-keeping; Development of virtual reality technology; Development of 3D TV
; Widespread adoption of internet shopping; Widespread use of Social Networks on the internet; Development of robotic systems and autonomous automobiles; Discovery that planetary objects, such as moons, around stars are very common; advent of AI, quantum cryptography, and crypto currencies.
So not a lot went on/going on in my lifetime.
As to anything else, well we have become a lot more open and relaxed in many ways, particularly as regards sexuality and gender issues, with homosexuality being decriminalised, for example, and this perhaps allied to religious notions becoming less important for so many. Education for children probably has improved in many ways - no caning or smacking, for example, and where I had lots of that - and where the mental lives of children are taken care of better now probably. To counter some of the benefits, we have social media and the ease of obtaining pornography, both of which are having negative effects for children and something I never had to contend with. And it seems that good old money-making has driven both without concern as to the nastier effects of either.
Oh, and we know a lot more about how other life behaves, especially the more intelligent and/or social ones, even though many humans still seem to be
carrying on regardless as to such knowledge.
