What "barrier" are you talking about? Surely in a developing country having a human code instead of using a no-code tool, is more likely than in a developed country, as humans are more expensive the in latter??
There is a 2-3 years coding barrier till you become a "Junior" dev and can get hired. It requires access to quality education which people in developing countries simply do not have.
But since they are looking to earn money as well, they prefer to use no-code.
I'm talking from experience and from numbers: out of 60k no-code experts that we have, most of them (95%+) are from developing countries and not from developed ones
