I don't think anyone is suggesting that those blocks actually were cast in woven fabric bags. It's just one embodiment to exemplify the design spec that's being presented, not the actual implementation spec.

The amount of pressure required at the injection port is proportional to the sectional area of the port and the height of the stuff that's pumped in. The smaller the port the lower the force required to push the stuff through (within practical limits, of course). The force at the port doesn't need to neutralize the entire weight of the block. It only needs to overcome the opposite force imposed by a relatively small column of stuff and the sectional area of the port, and that could be a tiny fraction of the total block weight.
If the "slurry" was heated a bit, its viscocity likely would decrease, making it easier to inject.
And yes we might expect to see evidence of other "advancements":
- How about a 200 year construction project to erect a bunch of enormous pyramids made from many millions of multi-ton blocks bearing a total weight of many millions of tons of masonry?
Or quarrying, shaping, and lifting solid granite blocks, each weighing 50 to 80 tons, and transporting them 600 miles to the construction site?
Or being able to level a 13 acre perimeter of rough bedrock within a precision of 3/4" from perfect horizontal?
Or a 100 yard shaft at a 26 degree angle, half of which is through solid bedrock, the other hand through horizontal courses of masonry, and the full 100 yards of which has a linear precision of barely 1/50" of an inch?
And let's not forget the 75-ish solid black igneous boxes weighing about 75 tons each with sharp inside corners and tightly matching lids weighing up to 40 tons, in narrow catecombs underground at the Serapeum?
Not to mention all those 800-2,000 ton blocks in Baalbek.
I'd say there is plenty of evidence that the original builders had a whole lot more skills up their sleeves than just "pour and cast".

I think it depends on the ancient culture(s) and the pressures they were forced to confront.
It also depends on what happened in the intervening millennia that caused their demise.
As is suggested at the Baalbek Sanctuary, subsequent cultures may have adapted the more ancient infrastructure of early cultures to the point that the earlier the work, the less recognizable it is.

And I believe it's quite possible that this phenomenon of "ancient tech passed to the hunter gatherer" has happened not just once, but likely many times, as nature repeats its cycles of creation, building, and destruction, over and over and over again throughout the eons.
How can any of us ever know, when all we can do is think?
