The
expensive pricing on RAM and SSD storage in Macs makes future-proofing a difficult proposition.
If you plan to keep your Apple device for more than 5 years, it is important to do some research and spec comparison - to use an analogy, Intel kept its processors artificially limited to 4 cores from about 2011 to 2018 (Sandy Bridge to Kaby Lake) for profit and market segmentation, until AMD succeeded with their new Zen architecture, and Apple was with both Intel and AMD in that period. RAM capacities also stagnated during that Intel period, sticking to 8-16GB for most mainstream configurations, and not upgradable in most Macs.
Applications were built in both macOS and Windows for those processors - if you wanted more, you'd have to pay for expensive Xeon (i.e., Mac Pro) or Threadripper products. Now, Apple makes M5 processors that blow those old systems away, even in the base configurations, with excellent battery life.
The runaway success of the MacBook Neo shows that a lot of users are buying computers for today, not tomorrow. The AI and RAM cartel-induced shortages of memory, SSD, and hard drives are forcing people to do more with less, probably for the next few years, whether or not the AI bubble bursts.
M5 Pro and the base M5 (particularly their
full-spec 4 and 6 S-core configurations) are great value products, too. You get diminishing returns with the M5 Max - only extreme use cases need that much power, justifying the high price. No doubt the M6 will build on that capability - to me, one of the major "future-proof" features in upcoming Apple Silicon will be native AV1 video encode, as companies like YouTube have already switched over to the more efficient codec.
Buy the device you can afford that meets your application needs - it's pretty difficult to predict the future. I think the AI capabilities are inconsequential, but that's just my opinion.
