"Home" computers from the 80th continue to exist as virtual machines, their software will probably survive a lot of hardware/software from today: even if you would emulate todays hardware to run todays software in the future, it would be dependent on many unspecified network interactions nobody can reproduce in 20 years. Vice versa, when you buy a lamp today, its much more unlikely that it will have a replaceable, standard socket bulb. Instead more likely a "lifetime" proprietary LED module which will fail 1 usec after the manufacturer has stopped offering replacement parts. Not to speak of a quite exhaustive matrix of incompatibilities between different dimmer types and LED high-voltage converter circuit types.
