The boomers benefited from technology developed by their parents.
Why does this sharing stop immediately when it no longer benefits said boomers?
I am unsure how the benefits of technology can be stopped from 'sharing' when it no longer benefits said boomers? Younger generations have very much benefitted from the technology developed by the boomers. As, of course, the boomers did from the generations that went before.
I don't deny that today's young people face many challenges. But they are different to the challenges faced by previous generations. There is no generation in recent history that has had any easy ride.
The world has completely changed since the boomers started out in life. I challenge the myth that boomers have had it better, taking everything into account, than the younger generation will have had when they get the boomers age now. However, it is really subjective, depending on how much importance an individual places on each component.
HTML and HTTP were absolute garbage. The only to reason they achieved widespread adoption is because they were free while competitor products charged a license fee. The internet is littered with suboptimal or outright terrible choices made because boomers started a long tradition of being too cheap to pay for quality.
We don't have the luxury of hindsight on the results of suboptimal or outright terrible choices of your generation yet. But when it becomes available, expect an almighty kicking.
