Our cognitive biases can easily skew our thinking and judgement. Can you not envision an economic environment where potential opportunity costs are outweighed by, hint hint, inflationary pressures? Or has your recency bias and possible lack of historic study clouded your own ability to comprehend the wider point I was making, which, by the way was initially offered in a friendly tongue in cheek manner. But this is a hill I am prepared to defend, because I have a feeling your biases might need shaking just a touch.
Not all bicycle redesigns confer technological 'improvement', most here would agree, technological improvements in the cycling realm are marginal these days, nor do all bicycle manufacturers try to dupe customers into buying the latest and greatest with consumerist tropes such as planned obsolescence, and these are not the brands I would personally be buying as investments in mobility and as I'm not interested in primate social status signalling habits. There are several bike brands which prioritise reliability, repairability, and backward compatability, and your knee jerk reaction to my point is telling of your own biases about the market! Please note, this is all shared in the spirit of good conversation and is not an attempt to win a d1ck swinging contest, I'm just pointing out that this is not a black and white issue.
Edit. I just realised you accused me in your first response of suggesting he replace his perfectly servicable current bike, that's beside the point as we would have to assume at some point he would need to do so anyway. Like a situation whereby a person owns two pairs of shoes at any time, they would not immediately throw out their first pair if they were offered the chance to own a second. The advantage of buying the second pair before inflation reduces the buying power of one's money is bolstered by the reduced rate of wear of each pair of shoe if they are alternated. This is before we get into other benefits of owning two bikes for resilience purposes. If inflation is sustained over a period, and there is not sufficient return in equities or interest bearing account, the people delaying purchase might be behind financially.
