From your link, what's missing for the OP is:

Thunderbolt, DP Alt Mode, Video Decoder/Encoder, SEP, Neural Engine, internal Speaker

Thunderbolt seems like the main missing feature. It's easy to see how someone could live a fulfilling life without running into the lack of any of those features. E.g. is there even anything on the Linux desktop that could take advantage of the Neural Engine or Secure Enclave?
