Here is my second attempt to explore this topic. I posted the first video, got about 1,500 views, watched it a few times myself, read the comments and decided I could do better, so here is the new and improved version.

Just watched the updated version. Does add some clarity.
So does nodes having only part of data due to 'charding' dont need to have a full data to get into concensus?
Yet another aspect I had not considered. I suspect Dan has thought about this. I wonder what Steemit, etc. are doing about this bloat?
MIRA is a big step. read here https://steemit.com/steem/@steemitblog/introducing-mira
Great overview as always!!
Great video :D
Disk space is cheap, party on
Good upgrade.
In reference to storage and bandwidth.
I work with virtualized computer systems; mostly VMware. Our storage solutions include HPE. On the storage side of things, HPE and other big name enterprise storage solution providers offer very flexible/scalable solutions to meet the storage challenges blockchain node block producers would need to have. Within VMware, the maximum supported VMDK size on an VMFS-5 datastore is increased to 62 TB. ... So the logical disk limitations presented to a client VM would be a bit of a problem. But the VM itself could simply take advantage of ZFS to overcome this, if a single large volume is required at more than 62TB. But I'm guessing a developed block chain node software has, or will soon have a method of breaking up the block chain data across multiple block producer node storage volumes. Also, there's linux file linking tools baked in to address problems like this; where individual volume sizes are an issue and you need to reference files physical localed on a separate location or volume...
On the bandwidth side of the conversation... I'm not as familiar with the exact problem because the manufacturing facility I work at doesn't use high bandwidth on a WAN (Wide Area Network) basis. But I have little doubt that in large cities, a blockchain block producer node could purchase multi-GB/s WAN links, perhaps even with hot failover connections.

I wonder how Hedera Hashgraph’s approach will solve this and if it will have the attraction due to this?

I think FUD is the right term here. As other folks have mentioned, operating a BP only requires a recent slice of the blockchain and an anchor point to a shared history. People don't freak out about this, but Bitcoin clients don't re-investigate the entire history of the blockchain on every transaction, they use a compressed, provable representation of history.
This is an extremely common problem in large scale systems today - the common solution is an Online system that processes data live, and a Warehousing system that stores and analyzes the gobs and gobs of data generated over time.
The analog here is BPs having an online system working on the active "tip" of the chain and an offline system creating new history anchors.
So in about 1 year BP's have to spend an extra 100 dollars. Im fine with that
I am a simple man, I see marketingmonk post, I watch.
Tanks for that Video explaining Blockchain Bloat, but there was low attention on the solution.
You could have researched on cardano before making this new Video.
For the Bryan an Shelly release watch here.
