>"Software on a computer is useful. Networked software is more useful. Cloud and IaaS is really useful, SaaS is a really really useful"
I actually prefer the reverse progression as the closer it is to my computer / my server the less I spend on feeding somebody else's insatiable appetites. Being connected is one thing. Giving somebody else more and more control over your business is totally different.
Yes, you're right, but i would take the meaning that understanding Software development and deployment and how that can be leveraged is a literacy. There's tons of IT transformation disasters because the companies upping their literacy get stuck with knowing the words (SOA and Agile) but don't know how to make coherent use of them.
Most projects these days are IT projects.
Think about it like a dev, Software on a computer is useful. Networked software is more useful. Cloud and IaaS is really useful, SaaS is a really really useful and knowing when to use each to actually get stuff done is the most useful of all.
