My last job before Google was working as a security consultant to SMEs. My experience working intimately with some 400+ such companies was that of businesses with less than 40 programmers, around one in 10 companies had one developer who could build something durable and follow "industry standard" precautions and practices. All the others had zero. At Google nearly 100% of developers are of that same quality which was exceptionally rare in industry at large.
