I agree. IMO, It will turn out like ATMs did in the past. The thieves got into them and they got bigger. Soon, they won't be the "pretty" packaging that's going on now to get people to sign on. It will be heavy and sealed off, even from maintenance. Once it meets it COA, it can be left in place to "die".I can already see gangs of thieves stealing Nvidia GPUs out of these server boxes. This great idea will likely die as quickly as it was born, maybe even quicker.
A sealed unit would require no maintenance, and as each gpu died, it would be put offline and the node would become "slower" but still useful. Think how older components were "potted" to keep things hidden or to aid cooling with older style heatsinks.
If they put these things with "starter homes" and promised the happy new home owners a discount on their electricy bills, how many do you think will fully read the paperwork and understand what they are signing up for? And when it comes time to sell - well, reminds me of the solar panel thing
