That, and you have to take into account each person’s available hardware and resources.
I have an under powered 10 year old desktop, a resonably specd 5 year old laptop with a busted screen, and 8 Raspberry Pi’s (3s and 4s). And can’t currently afford better hardware.Sometimes clustering those Pi’s makes sense.
You can use whatever you have to hand.
Sorry, couldn’t help…. This meme just popped in my mind!
