Hopefully we're wrong and BD somehow magically gets better leadership and actually starts to become developed via industrialization.If you are 25 years old now, another 65 years to become 90 years old. I do not expect BD can develop at that point. It is now an underdeveloped or Least Developed country. The next phase, the "Developing" stage takes a very long time and for many countries, this stage does not end at all.
BD is behind in industrializing and it cannot design and manufacture mechanical/ electrical machines. Copy-pasting of many easy technology products is a good sign of progress. However, BD cannot even do it.
So, when do you expect BD will start manufacturing machines, engines, motors, parts, and components in commercial scale? Is it in the next 65 years? Hopefully, but it will still remain in the developing stage.
Note that China is still in the economic developing stage although it can build its power plants (also nuclear) and all other plants, mills, and factories with its domestic technology and manpower.
How about our Golden Bangladesh? Can it build by itself its power stations, fertilizer/ chemical plants, or steel plants in another 65 years? I doubt it. At least, I do not find any symptom that it can do such things.
