Re: takes time for Core Software to be cloud native and to be mainstream.
There are some vendors who do offer cloud-native software in the core but the trust, expertise and ability to offer end to end solutions across the network are lacking.  Finally, the investments required to change over 3-5 years need to be justified with a biz case and the lack of clarity with 5G is hurting it.

takes time for Core Software to be cloud native and to be mainstream.
It's rather easier to blame each other but it's all about money and business case. Operators want 'cheap' so to justify the transition or business case while vendors and current technology doesn't match the needs. Added to the skill set issues, architectural limitations, and regulatory needs make it too complex to adopt in core domains. In non-core (be it IT or support systems) it is rather easier to move. Or big guys with other businesses could lead like Rakuten. 

But with hundreds of Gbps or close to Tbps traffic in a centralized location making the move to cloud yet meeting the regulatory requirements, changing the mindset from pets to cattle take some time. Distributing to the edge was a good idea and will happen but the current infrastructure (be it infra or fibre or IX peering/transit points) makes it very confusing to the majority of the emerging markets.
