Economically, the Swedish approach is so much faster, and less labor intensive too; given enough volume it's advantages are self-evident if labor and electricity costs are roughly the same. We know this because of what eventually happened to British ship building in the 60's to 80's; British ship building was very labor intensive and staunchly anti-automation because of the militant union movements in the UK at the time. Competition from Sweden, Korea and Japan wiped them out, after 150 years of global dominance.
