yep, both are significantly different in many way, houses built 50 years ago have a lot of differences to modern houses. Software from 50 years ago, is also significantly different but the fundamentals of both are the same, foundations, walls, roof trusses, siding, filesystems, operating systems, processes, threads, data structures etc. We may use Go instead of C and we may use engineered lumber instead of Douglas Fir for door headers.
