What do economists think of Marx’s Capital today? Have there been any debunkings of it?

To quote one user on the matter. 

>I mean, as the name implies, it's a study and critique of capitalism (and the classical economics of the time) that stands unchallenged for 150 years and counting. Everything that has come since in the field of economics has been in reaction to Das Kapital.
The fact that its publication is alone responsible for forcing the shift in bourgeois liberal economics from classical to neo-classical, Keynesian, whatever, and that none of it has managed to "disprove" or make Marx obsolete in any way whatsoever, should tell you just how much of an influence Das Kapital truly was, and still is, on everything in economics and politics.

>Only one group of economists were not caught off guard by the crisis in 2007/2008, and it sure as shit wasn't the Keynesians...

Links to sources would greatly be appreciated. Thank you.

That user's quote is pretty nonsensical.  

* Marx's Kapital in no way predicted the 2008 crisis.
* Plenty of mainstream economists did predict the crisis
* 'The keynesians' aren't even a real thing and shows their ignorance of the field.
* Das Kapital in no way 'forced a shift' from one type of economic thinking to another.  To credit the shift to Keynesian thinking (or any shift) to marx is laughable - Keynes's *General Theory* was published like 70 years after Das Kapital, and economic thinking had already shifted multiple times since then.

The general view on Das Kapital today is that it's an interesting book for historical purposes, and got some things right, but also got a lot of other things very wrong (such as the labor theory of value).  It's not actually a book on economics as much as it's 'political economy' and an attempt to describe the process of economic history in a Hegelian sense.  Marx and/or Das Kapital is not taught in economics curriculum because Das Kapital didn't contribute meaningfully to modern economics, which is based around mathematical modeling and empirical evidence.
