That 2013 model (at least the late 2013 model that I have) añready has an SSD. RAM is soldered if I remember correctly.
Thr issue that mine has - aside from a broken hinge over time - is that one of the thermal sensors is fucked, so the machine puts the fans on full and heavily throttles the CPU. Before that happened (last year) it was a solid machine.
You should check out Tool-Assisted Speedruns om tasvideos.org, then. They use some of these techniques to do RNG manipulation, among other things, to improve game times.
I don't think anything meaningful will change. We'll have higher-definition video and that'd be it. Business practices and the client-server model wouldn't change, and the internet as we know it wouldn't change. Files will just get bigger (and arguably morr bloated). That's the trenf we've always seen.
It might be easier to do distributed computing in some fields, and there could be interesting opportunities for mesh networks and internet of things in addition to data collection, but it'f all be the same corporate data sales stuff we see now. There won't be a paradigm shift because the current culture is built around business.
