Over the years, there have been two conflicting visions for what Bitcoin should be.
The Core development team what Bitcoin to be digital gold settlement layer. A censorship resistent store of value for settling low volume, multi thousand dollar transactions, that costs hundreds of dollars per transaction. This is because the higher transaction fees are, the higher the "security" of the network is.
The other, competing vision for Bitcoin, and Bitcoin Cash, is that it should be a way for every day people to make every day transactions. They believe that fees per transaction should be measured in cents, at most. This vision sacrifices some amount of security, in order to allow mass adoption.
There are more complicated arguments, such as mythical "layer 2 and layer 3" solutions, called the lightning network, that could be deployed on the network, so as to help with scalability. But these solutions are perpetually 18 months away from completion.
Mostly recently, the settlement layer, high fees faction "won" by stopping one of attempted upgrades to the network, and the other side responded by forking the network and going its own way. That is Bitcoin Cash.
The sole reason for the existence of Bitcoin Cash is pump and dump + (covert) ASICBOOST by Bitmain (largest chinese ASIC manufacturer) leading to greater centralization and an unfair advantage.

Besides that, Lightning Network can be deployed much quicker. In fact, it already runs on testnet e.g.: https://github.com/LN-Zap/zap-desktop / https://www.youtube.com/watch?v=dhpg_8D2FPI
So how is bitcoin core going to scale ? Take a look at this: https://www.reddit.com/r/Bitcoin/comments/7cn5dj/so_how_is_b... (Schnorr, RSK, Segwit, Lightning and more)
So in 3 whole months, segwit has scaled the network by a measly 5%.
All the stuff you are talking about will likely end the same way.
You can see the updated hash-rates here: https://fork.lol/pow/hashrate
This might equalize with BCH's fork today, which will give them a free difficulty adjustment.
The hashrate quickly jumped back to Bitcoin after the difficulty changed.
This news is essentially equivalent to saying "On November 13th, Salesforce outspent Apple in cyber security. This is one of just a few days in all of history where the security spending for that day for Salesforce exceeded the security spending of Apple for that day. Apple is expected to fall into a death spiral soon."
This flip of "profitability" has miners chasing the most $/second. Mining pools even have automatic switches that change networks depending upon the current network state.
The original difficulty algorithm is very slow, and the BCH "EDA" difficulty algorithm is predictably chaotic in a way that guarantees these immediate extremes of profitability vs unprofitability. It is being patched with a stable 144 block average presently (the next block at time of writing), at which point the swings will not be as extreme.
The reason it started around Oct. is because the price of BTC had historically made BCH unprofitable at almost any difficulty, but a positive BCH price swing has changed that.
Alternatively Bitmain has just plugged in a new batch of their ASICBoost
-Some swedish guy who claims he is the CEO of bitcoin cash. Who is also a pirate party member
-Roger ver, who has been kicked out of US after serving jailtime.
-Wright, a guy who impersonated satoshi nakamoto and was exposed
+ alot more.
these people want to take control of bitcoin and make it a centralized currency.
Didn't Satoshi (before he disappeared) advocate for the BCH approach to scaling? That's a pretty respected name.
