It sure isn't fun when you spend $5000 highest end Mac Studio to get dwarfed by $1000 M4 Pro chip a year later on a Mac Mini. I do think Apple is way too dwarfing the last gen chip as if spending more for a prosumer Mac means nothing.
You might have missed this, but a computer you bought a year or two ago being slower than a cheaper computer bought today has been happening for nearly the entire history of home computing. Things were stagnant for a while there due to Intel's issues with chip development, but mostly rapid improvements are the rule, not the exception.
You would have
loved the PPC transition--in early 1993 a top-of-the-line professional Quadra 800 started at $4680; just over a year later the consumer-grade Power Mac 6100 was announced at $2000 with the same amount of RAM and a slightly larger hard drive, and depending on the benchmark you use was between 1.6 and 4 times faster (its floating-point performance, in particular, was
massively higher). Less than half the price, twice the performance.
Same thing happened with the 60x to G3 CPUs, and again with the Intel to M-series transition, as well as many,
many times in between, regardless of whether you were an Apple or Windows user.
The absolute-top-of-line iMac I bought 4 years ago, with a 10-core i9 CPU, is
30% slower than the M1 Max laptop I bought about a year later for around the same price, and that iMac's CPU is now slightly slower than my
phone, which cost a quarter what the iMac did and fits in my pocket. But I'm not complaining, much less advocating Apple stop improving things so quickly so I don't have to feel bad that I got exactly what I paid for at the time and then somebody else got an even better deal a year later, and someone else will get an even better deal than them the year after.
You buy a computer. There's something way faster available for less next year. That's how it works.
