I wonder how a programmer from the 80s would react if they were given a time machine and this was their first experience with modern programming.
"Oh, you're only downloading the software you need, when you need it, from the network? That's smart, you must be really smart to fit all these pixels into 640k"
"Who cares if everyone will need the 'core'. Back in the 80ies the rule is: if you can avoid a goto, doso!"
It's not like dumb thin clients and mainframes would be a new thing.
