You can point to a lot of periods in history where everything changes rapidly for at some points a couple of centuries before settling down again. It's hard to say if the modern period is unique or just another period of tumult between long stretches of calm. I'd caution against the notion that history is a science.
Nobody can know the future, but some things are clear:
1. We are a lot more interconnected than in the past (every human civilization that wants to interact with others can do so... or was even forced do it, not very long ago).
2. We are a lot more self-aware than in the past, en masse.
3. We are a lot more structured in our large scale scientific approaches, and we have a lot more science centers working in parallel, widely distributed around the world.
Assuming peaceful conditions and no Venus-style global warming, things will stay hectic for the foreseeable future.
I don't think interconnectedness presages rapid social change. We could just as easily settle into a sort of long quiet period where people are more or less accustomed to the way society is organized and institutions have been reformed to adapt to present day issues. After the industrialization of the 1early 9th century there was a fairly stable social arrangement until WWI swept everything off the map. It isn't impossible to imagine a situation where WWI didn't happen and the Belle Époque stretched for a long period of time.
That's one way to look at that period with rose tinted glasses :-)
There's a reason Marx & co wrote things during that time.
WW1 was just a more violent outburst of many frustrations, national, social, etc.
Marx wasn’t writing during the late 19th century. The Revolutions of 1848 were the backdrop of their work.
Whether history is or isn't a science is completely orthogonal to how unique a period is.
The modern period is unique due to the amount of resources being exploited per capita being unprecedented compared to any other time in human history. Although in the future it's possible that that number will trend down, for the time being our current prosperity is only enabled by copious amounts of energy spent on modern conveniences, particularly infrastructure, appliances and utilities.
If we need progress, and we do, because nobody wants to die (of disease, old age, whatever) and everyone wants a good life (not one doing backbreaking work or even doing dishes), then that means trying to progress is an inevitable aspect of being human, not a an aspect of the "bourgeois epoch".
It's not the bourgeoisie doing stuff, it's just us, humans.
So if we are progressing and we build upon progress, then progress accelerates, it's only natural, since we have more stuff to build on top of.
That's what's actually melting social conventions and perceived stability.
And I don't think anyone has a solution to this problem, yet.
I think this is misunderstanding what Marx was trying to say here. Marx saw the bourgeoisie (fancy word for "owners", that's all) as a product of forces, not a cause.
The cause is the specific form of economic management / ownership in the current era -- capitalism. The structure of private property, or ownership of production by private entities; which unleashes the profit motive. Which rewrites and restructures everything in its path. Workers and owners are just doing what's required of them to keep feeding this furnace -- and their tummies.
Yes it's humans doing it. But they're doing it in the context of filling their stomachs. The point is that the way that they filled their stomachs changed. With consequences, good and bad.
Disagree strongly with this phrase "we are progressing"; this is value laden, and hand waving. There is definitely a motive force driving things -- profit extraction -- but the word "progress" implies inevitability and a singular direction as well as a positive aspect. I think we can be more scientific than that.
And yes, agreed, nobody has a solution. But I think Marx is among many who have a line of useful analysis about what this is.
I do feel like Marx "slips up" a bit there with the "senses his real conditions of life"; this feels like "Younger Marx" of Manifesto/German-Ideology era and not older, mature, cynical Marx of "Grundrisse" and "Capital". I think the latter recognized that at no point are the "real conditions" visible or confronted, and that all is 'obscured' by ideology and the pursuit of market domination and exploitation.
The words of "Younger Marx" there were easily twisted and exploited by people with awful motives and means and brutal simple minds. Later Marx ... they didn't understand.
The "cures" in the 20th century were on the whole written by people with far simpler minds and uglier motives. Their actions don't take away from the value of Marx as an analyst and critic of capitalism.
The phrase "dictatorship of the proletariat" in particular has a very unfortunate history and ... interpretation.
I assume you are overlooking the little things like the abolition of private property, or central planning of the economy on purpose?
