Exactly. Bitcoin Cash may have greater scalability than Bitcoin, and most old altcoins like Dogecoin and Litecoin. But, its low transaction activity shows us that people really don't care about the technical aspects of the underlying cryptocurrency's Blockchain network. It's impressive to see a joke cryptocurrency like Dogecoin without any improvements in scalability whatsoever, being superior than Bitcoin Cash in terms of transaction activity. Which means, that people are on the hunt for tried-and-tested coins that actually provide real use cases (and value) to the mainstream world, than just hype. In Bitcoin Cash's early days, everything was full of excitement leading prices per coin at $4k across the market by 2020. But right after many people discovered the centralization risks of huge block sizes with Bitcoin Cash's inception back in 2017, we've seen a decline of interest over the past months.

Bitcoin Cash's hash wars in 2018, greatly diminished the cryptocurrency's reputation within the mainstream world. Given the events of Bitcoin Cash's huge block size, I doubt that Bitcoin will increase its block size anytime soon. While SegWit has increased the "block size" (now called "block weight") to 4MB, the Lightning Network takes care of the rest by providing instant transactions with low fees without the need for enormous block sizes (unlike both Bitcoin Cash and Bitcoin SV) which prove to centralize the entire Blockchain network.

Nonetheless, Bitcoin's SegWit + Lightning Network may be all it needs to scale for the foreseeable future. Increasing the block size is not a priority at the moment, as Layer-Two solutions alleviate the situation for a pretty long time. Until the Lightning Network becomes "clogged up", developers of the main Bitcoin blockchain won't be increasing its block size anytime soon. Just my opinion
