That's how cutting edge tech has always worked.
Imagine buying a shiny new PC in the 90s only to see it become practically obsolete within a year.
Or you could buy a PC with a Celeron CPU, which was obsolete way before launch.
The 486 chip came out in 1989. The 586 came out in 1993.
The pace of change ("practically obsolete") is different then and now.
Hardware definitely has longer lifecycle than AI model releases at this point.
You don't see Nvidia and AMD fighting every other month over the latest cards.
That's not the experience of owning a PC I remember from the 90s at all.
