When we were in a low/zero interest rate environment - there was a growth at all costs mentality among investors (and therefore management). Since investors didn't give any bonus points if a company was able to operate profitably - might as well depreciate to the max allowable by accounting law and not show a profit. In fact - not showing a profit was actually seen a positive features/badge of honor for a stock.

Now that interest rates have gone up, investors care about ability to generate current cashflow/net income and are prioritizing rational PE ratios - depreciating expenses over a longer time horizon (closer to reality) makes sense.

I bet there are lots of places that parallelisation makes more computers within the ballpark of acceptable performance perfectly cromulent to keep around.

Heck, my 2015 mac is a perfectly serviceable media player when I watch sport.
