They will steal your intellectual property and leave you with nothing. It’s what they did to the US. Korea is a closed society, hostile to outsiders, and they would have zero intention to share any benefits with you. They simply want your intellectual property.

There is a saying. The Koreans work 8 days a week!

Selling Comp. and/or ideas makes few people filthy rich.
WHO gains from these activities ??? Only few people and their banks.
Does it make the country PR ? No.
S.Korea made itself a huge name by BUILDING and PRODUCING: cars, home appliances and mobile phones.
Israel does NOT produce and does NOT build NOTHING.
