I learnt and did coding between 1991 to 2002. After that I almost never learnt or practiced. But I know what exactly going on during the shift form desktop apps to web apps to multi tire apps to Hosted solutions to SaaS to whatever we are this day! My team of developers were doing coding, and I know what they can do and what they cannot do. I trust this answer should help you to see through the answer.
