I'm skeptical of anyone with a long, significant career in software that claims "no bugs or errors." Especially if they tout C++.So either we have encountered the "World's Best Programmer, Ever" or we are being trolled. Now days we don't believe anyone's claims in this field unless they demonstrate it. (Considering an estimated 80-90 percent of job candidates misrepresent themselves. ) There's one sure way to find out:
Please post some of this amazing code on GitHub or publically accessible site of that ilk.
Extraordinary claims require extraordinary evidence.
Actually, I'd just take some metrics for a ballpark idea of how complicated his programming is. I think that there certainly exists examples of working programming that can be produced correctly. Obviously not having to change a program in decades is certainly a factor in his favor, many of my programming errors result from modifications and I rely heavily on testing to ferret those out.
Some metrics of complexity I'd be interested in could include line count of code in total, programming language(s) used, number of modules, average size of each module, number of bytes of the code in total, number of bytes of a compressed archive containing the code, etc...
