Yes, laptops have a lifespan, my 2013 macbook pro is going on for 10 yrs, I would have loved to have spent money on RAM upgrades, SSD upgrades, a new screen, but I could not, not upgrade capable, then after 10 yrs, have a decent laptop, I was forced to update to an air, would rather have bought the PRO, but it was not within my finances.. There a laptop not bought, I would have over the last 2 yrs of the macbook air, invested in upgrades, not done...
I would buy the base model M3, no question, if I could over the next 3 to 5 financial cycles, invest in upgrades, one cannot justify spending $3200 now, but $500 x 3 to 5 yrs, is about do-able.. Why can Apple not see the benefit of encouraging upgrading? No they will not know I did not buy a laptop, which is a pity, as they are great, but to outlay $3200 or over R60 000 to R100 000 for a laptop, I cannot justify, but to spend R3000 a year on updates/upgrades, that is viable...
