Windows 10: Question: Would it be wise to upgrade from 4 GB DDR4 RAM to 8 GB DDR4 if not DDR5 RAM with...

In 30 months, I'm sure I can find more Windows PCs with 8 GB of DDR4 if not DDR5 RAM not over $369.99 plus a 6% sales tax, but with free shipping on sites and apps like Amazon. Yes, I have a 128 GB SSD. 30 has become my truly favorite number recently for many reasons which has a lot to do with thinking 30 years into the future every day, inspired by 1st degree felonies in Florida, Class X felonies in Illinois and such.
