We also seems to have much more appreciation of cost. Instead of renting a bigger remote server, we choose more efficient software to install or revamp our code. Instead of getting a snazzy new gaming notebook every year, we're digging old Linux machines out. We don't all have top-of-the-line Internet or mobile plans, so the stuff we built will work as well in the Bavarian backwoods as in Dallas, Texas. Instead of hiring a bunch of staff to do tedious labour, we automate it and ask for volunteers.
