I think on the whole, the internet is massively a positive thing. Of course, it has down-sides, some extremely worrying - as a parent of two teenage boys, despite putting all parental controls on wifi and mobile networks, I worry about the effect the more extreme forms of online pornography might have on them. I've had open and honest discussions with them about this.
I'm in my 50's so more than old enough to remember pre-internet life. Shopping for instance - you went to the local town and bought the best of what was available - hugely reduced choice, no online reviews to assist you, paying to cover retailers rent and staff cost overheads etc. Now, choice and information is limitless. Yes, town centres will have to change as 'bricks and mortar' retail is under pressure, but everything changes sooner or later.
If I want a holiday, I can book my own AirBnB, my own car rental and flights from my sofa, and get the best prices. I can even have a look round the place before I book on Google maps, see what the menu looks like in all the restaurants, check out the attractions etc...
Then there's information for study - my kids are doing A levels and GCSE's and the wealth of free information astounds me. They can find literally anything they need in a few minutes - and learn valuable lessons about the accuracy and completeness of various sources, which helps them to critically evaluate information.
Entertainment has been transformed - YouTube, Netflix, Amazon Prime , music, video, TV... When I was a kid we had 3 TV stations and no video recorders...
So yes, the internet is, on balance, an enormous positive.
