I'm a firm believer that future proof (for the most part) is a marketing strategy that apple and others employ to manipulate people to over buying.
Apple Silicon is so powerful, there is almost no reason to pay apple upgrade prices when the base model is almost always sufficient for most people.
I have a M1 MBP, base model, its been working great for 6 years, I'm glad I didn't pay for increased storage/ram.
The Neo, people are happy with 8GB of ram, and an iPhone processor. They're editting videos, photos, doing things that were once used to justify the upgrading the ram/processor. Thunderbolt storage is a viable alternative to paying the apple tax for more storage.
