At about 50 - 60 000 years, then, the limit of the technique is reached (beyond this time, other radiometric techniques must be used for dating).

I don't believe Scientist are anywhere near "absolute dating" as you
call it. All the methods used are based on assumptions. The link below identifies three assumptions that have to be made in order to 'believe"
the accuracy of these dating methods: 1. The intial condition of the subject 2. The system has been closed(no change to its enviroment)
3. The radioactive decay rate has remained constant.

I could find many examples of failures using carbon 14 dating because
it has been used on objects we can date historically. Presumably the cause has been enviromental contamination. Yet it is assumed that these other methods which can't be verified are reliable.
