Only 5? The raspberry pi 4 has nearly the same computational power as the servers I did my first research projects on and uses something like 1/100th of the wattage? I actually how no idea how much it cost but I imagine it was more than $5*50
5 orders of magnitude means the number of zeros. $50 -> $5,000,000
well, a lot of the cost of medTech equipment lies in the certification and SLA.
there's a reason why a medical rated scissor is 1000 USD and the same sold on amazon is 20 USD.
