We're at an interesting point in the future of currency and what money will become. Keep in mind I'm thinking pretty big picture, long-term stuff.
Governments of the world (along with Wall St investors like Warren Buffet) hoped Bitcoin was a fad that'd just go out of fashion and die off but instead the exact opposite has happened. Even if you aren't especially into technology or cryptocurrency, everyone these days knows what Bitcoin is and the value is frankly absurd. And a huge ecosystem of "altcoins" has sprung up to utilise the blockchain in various new ways.
There are already anonymous cryptocurrencies, the biggest being Monero, which unlike most other cryptos does not have a public ledger that shows you "this wallet sent this much to this wallet." I believe once we do go "cashless" either Monero or something else like it will take its place. For real world transactions it's very easy to use. Just scan a QR code on your mate's phone, type in how much you want to send, and boom.
The volatility of crypto can be avoided with stablecoins, which are typically pegged to national currencies. For instance Tether is pegged to the USD and is always worth exactly $1. From a technological perspective, since Tether is just a token that runs on other blockchains, there's nothing stopping someone from putting Tether tokens on a Monero-style privacy-focused blockchain platform, which I am sure already exists or is in development somewhere, probably by multiple competing teams.
The Bank of England sees the inevitability of cryptocurrency shaping the future of money if they don't compete. But perhaps more importantly, they're also worried that if everyone only ever uses contactless payments, direct debits, and bank transfers, they're actually using private bank issued money rather than BoE issued money.
The BoE doesn't want to concede control of the monetary supply to either crypto or banks. So they are going to create a CBDC. They don't really have a choice and Jon Cunliffe, deputy governor of the BoE, has only made his position on this stronger over the years. For the same reason, they are also dedicated to keeping good old physical cash flowing.

I'm very curious as to exactly how a BoE issued CBDC would actually work. Certainly very differently to a decentralised cryptocurrency I'm sure. But in entering the digital currency space they are competing with decentralised cryptocurrencies which have their own benefits over state backed currency.
So I reckon the real battle in the future will not be contactless vs cash but rather state backed, central bank controlled currency vs decentralised currency once everything is digital, however long that takes.
This only really scratches the surface, because blockchain technology is already being used for a lot more than simply moving cryptos from one place to another and this trend will only continue. I believe when people have the choice between a CBDC and decentralised finance (DeFi), some will choose one and some will choose the other, but either way the ones to hurt will be banks. And Jon Cunliffe has stated in no uncertain terms the BoE is not going to protect the banks if they fail to move with the times:

Very interesting times ahead.
Anyway, this isn't a crypto thread so I'll shut up now. Ultimately I do reckon we'll eventually go cashless (not in 15 years though) but once we do, we'll see a "battle" between central bank digital currency and cryptocurrency. When all currency becomes digital, central banks are suddenly in direct competition with crypto. And frankly crypto's had a big head start and will innovate much more rapidly than any central bank.
For what it's worth I bought £300 of Ethereum a few years ago which is suddenly worth over £10k. I've reinvested that primarily into Cardano which I believe will usurp Ethereum as the next dominant DApp platform.
