According to this article the Op Cit Bookshop in Taos, New Mexico (formerly known as Moby Dickens) still uses an MS-Dos computer to do a lot of their internal stuff. I'm not going to babble on for too long because I want you to read the article as I invite you to reflect on your current use of modern software and whether it is all really necessary. This bookstore hasn't seen the need to update their computer in 30 years, why should you?
On this site I advocate for the use of simple and time tested software, I use a eight year old Thinkpad T420 and software that was first written in the 80s and 90s to do everything on this website (along with everything else I can get away with). You'll also notice that my cookbook looks nothing like a typical online cookbook and that I advocate for a lightweight internet that isn't a burden on people with poor connections. I also encourage people to lessen the impact that social media has on their lives. There is no reason for you to get caught up in chasing trends and putting things in your life that never needed to be there.
Newer does not always mean better. To quote the scientist Nicholas Carr:
We assume that anyone who rejects a new tool in favor of an older one is guilty of nostalgia, of making choices sentimentally rather than rationally. But the real sentimental fallacy is the assumption that the new thing is always better. What makes a one tool superior to another has nothing to do with how new it is. What matters is how it enlarges or diminishes us, how it shapes our experiences with nature and culture and one another.
Don't convince yourself that you need to have the newest things and need to be taking advantage of the latest software. If something works there is no need to replace it.
