It depends what you class as improved, and what's important to YOU. I mean in 50 years a hell of a lot has improved, and something you didn't mention was modern medicine. I would love to live a simpler life, but I'd miss modern medicine. Personally it's saved me when I got a rare form of leukaemia, I think 50 years prior the treatment I had wouldn't exist, I think it was only developed in the 90s. But on the flip side something I mentioned in another post is that modern medicine also lets us exist for longer, I say exist because it's not really living after your 90, mostly people are immobile at that age, fragile, prone to infections & viruses and generally much weaker. But it sucks that governments just see statistics and come out with a later retirement age, like we're all sat behind a desk until we retire.
A lot of technology now is based on prior technology of course, it wouldn't be an [/i]improvement[/i] otherwise. Things like AI have dramatically improved our life, just like in the last example it's allowed medicine to greatly improve. But generally as you make something more advanced there's always more problems to iron out, and it takes time to do so.
The problems with phones (and most of our other tech) is that it's based on software to operate, and the problem is that there's so much to go wrong in terms of undesired functionality or "bugs". Coding software can get very complicated and doing it perfectly is impossible, so it becomes part of life that eventually something will go wrong with it. As a consumer you're kind of a tester, in that if loads of people report a problem it'll eventually get fixed.
I think TV's have greatly improved in the past 50 years. I mean those old CRT TVs where massive and weighed a ton! Moving it around was a pain, and the picture was so poor to todays standard... but then again it's not like you knew it at the time. I like how thin TVs have become, if you had a 22" CRT it took up so much space! But like you touched on there has been many gimmicks like 3D TV, do you remember when they brought out TVs with those LED colours behind them? They would change to the average colour of whatever that it was showing at the time - complete gimmick. Like most things they try to bring something to the market just so it'll sell.
I've never been into VR stuff, but the headache you got many people have also experienced, and I would too. It's because not everyones eyes are perfectly cantered. Most cases you can't even see the difference and you don't noticed at all because your brain is used to dealing with it. But then when you view two images that are cantered true and your brain isn't used to processing that it's where you get a headache.
It's not business sense to make something that will last forever, but if stuff lasted forever we wouldn't have nearly as much stuff as we do now because it would kill innovation. The explosion of modern technology has sparked consumerism, so now it's all about having the latest stuff, and some companies depend on this, not least Apple. It's not just the governments wanting to benefit, I think people in general want to be rich, but it always crosses the line into greed. Have you ever seen the show "Dragons Den"? It's where people are seeking investment for an invention or service trying to build a business, they pitch their idea to a bunch of investors. I like that show, but I don't like their mentality, greed shows right though. People go on with some really good ideas or products, but the investors aren't happy unless they can practically take over the world with it and earn so much money off it. There's no real intent on promoting a product or idea because it's helpful, earning a modest amount and then that's it. It's all what about the next product or how far can we g with this.
When it comes to cars again I think things are so much better. They're a hell of a lot CLEANER than they were 50 years ago (Although you could argue that the consumption of cars have increased dramatically to counter this), efficient, and a lot more safer. But again the more **** they put on a car the more there is to go wrong.. but like before half the time it's software, especially in those Teslas.
Storing energy is a very difficult task, and if it wasn't all our problems relating to energy would be solved. The very nature of storing a lot of energy in a small place is never going to be completely safe, that kind of comes with it. Batteries aren't the most efficient way to store energy and aren't where we'd like them to be in terms of reliability (for cars), capacity and charging rate, but it's the best we currently have for most purposes and they're improving all the time.
Like most things now it's supply and demand, and the problem with that is that you're going to have the problem with making whatever it is quicker and increasing volume, so how do you do that? Unfortunately for food is GMO and chemicals. I think bread is one of the worst things you can eat, just look at the ingredients of bread, there's so many chemicals in it, most of which are preservatives and cooking agents. But it's present in most of our food, it's tough to buy good quality foods nowadays because of the fact that the human population is exploding. Everything becomes a problem and it's these "solutions" that appear.
The governments are pretty useless and seem too busy arguing amongst themselves or trying to make the opposing party look bad than running the country. The government in the UK is a joke at the moment. It you watch any footage from the house or lords it's just like a zoo. They have the complete inability to manage the country on a basic level, there NEVER seems to be enough money yet they're all on £100,000+ a year. There's always some kind of controversial scandal on or sneaky money dodging going on. It's a joke that the guy in charge of the countries finances turned up to a event at a building site in a pair of £800 Prada shoes, what kind of a man who's been born into wealth like that know about setting taxes, social funding, and general money allocation? He chose to increase taxes further despite energy bills exploding and people suffering financially, and then applies to become the PM after he voted out the current PM. It's almost like a comedy and why I don't really believe or trust the government, I think a lot of them are self motivated and the interest of the country comes second. There's plenty of evidence to support this.
The world nowadays isn't a great place IMO, and I often think if I would want to bring kids into it at all. Everything is far more casual now, relationships, kids, marriage, it's all just take it & leave it. It's each generation gradually evolving this mentality because everything is available on demand, and everyone has rights to do what they want. It's super easy to get money in terms of loans and credit, and this has an effect on how people think about money, again for each new generation. As far as I'm concerned it's your responsibility as a parent to teach your child about this kind of stuff, but then that in itself isn't easy because of things I mentioned earlier such as work demands, etc.
