I buy the extra memory with the hope that it extends the lifetime of my computer. I can still use my MBP 10 years later. I bought a 15” Air two weeks ago with 16GB and I expect I’ll still be able to use it a decade from now. Have barely used the Air because my software is set up on my Intel. Will transition soon and will be able to compare performance.
