As shown on my website (which I understand most people here have probably read and don't need reminding), my table of values for various-sized black holes suggests that one with an average density equal to a neutron star would evaporate via Hawking radiation in 6.13E+76 seconds (1.94E+69 years). The black hole given as an example in the article cited would evaporate in 3.15E+75 seconds (1.00E+68 years). So it has slightly higher average density than a neutron star. This shows that his 4-month computation is consistent with the simple equation that Hawking published in the 70s.

The main assumption of the evaporation lifetime is that no additional matter will be absorbed in that timespan. How likely is that? We have X-Ray observatories telling us that matter is absorbed by black holes regularly, on timescales that are meaningful, continuous even. This should indicate to anyone with a brain that black holes don't evaporate away unless they are super-small and have a super-short evaporation lifetime. All other black holes GROW.

Given this conclusion, we have to decide if there really is an 'infinitely' dense singularity inside them, or if some natural process negates it. I personally don't believe that infinities of anything exist. Of course I'm not an expert in that subject, but I draw my conclusions from what knowledge I do have.
