upgradability

maybe self driving cars 

autonomous construction machines 

and humanoid robots 

need to be built to be upgradable 

so that new computing hardware 

and communication hardware 

can be installed 

for example in the future 

when 4g and 5g communication networks 

are closed down in the future 

so that only 6g and possible 7g communication networks 

are available 

then self driving cars 

autonomous construction machines 

and humanoid robots 

need to have their 4g and 5g equipment 

replaced with 6g and 7g equipment
