NHS budget grew in the same period 53%

Even if you ignore the massive injection for COVID it grew 39%. The NHS has far more money per pop than ever before in its history yet it cannot meet even the most basic expectations that a third world country would have, like people actually being seen by a doctor in a timely manner if they collapse on the street and an ambulance is called out. Let alone less urgent stuff.
That's why the idea Palantir or any company would ever want to "steal the NHS" is delusional. The NHS is a bottomless bonfire of money, it's the USSR in healthcare form and works just as well. The more money it gets the more dysfunctional and broken it becomes. Nobody in their right mind would want to steal such a worthless thing.
I don't know if it kept up or not, but the comment I replied to mentioned that in some years the budget was static so unless UK population somehow stopped growing or becoming older the effective budget per user has been effectively cut in those years.
But to your point, you may say population increased by 6% but you ignore the fact that thanks to life standards having increased there's also an ever-increasing number of old people who don't count as population increase but do increase the burden on the NHS.
Oh, and anyone who has actually had to use the NHS, or perhaps had a relative use it, particularly at the end of their lives, will have been very quickly disavowed of the idea that it is “world class”. This is not to say a US model is desirable (the US has the worst combination of various constituent practices/rules/structures) but other models are possible. The Dutch for one.
