We used original adobe photoshop from 1995 all the way thru 2014 by means of using a virtual box. It completely couldn't run after that.
It's good and bad to stick to what had always worked. I feel like the pro is the learning to be resourceful by figuring out ways to work with the limitations to produce unexpected results. The con, I guess it'd be the sticking oneself in a rut, where suddenly we become afraid of using something new.
I have to be honest. I grew up in abject poverty. We had no running water, sometimes no electricity, it was 120F outside, in a dog eat dog family (with a few exceptions). This programmed me to be resourceful but also to not use new stuff EVER, only as a last resort.
So, in some aspects, is good because I know how to get water out of a rock (sorta speak). But in other aspects, it brainwashed me to not want to try out new things. It pains me to use something new.
Thankfully, I love life enough to want to defend my alive status. This forces me to learn to use something new when I detect my need of it.
Why we had so many inventions in the 19th & early 20th century? Because we needed them.
Necessity mothers all invention.
