I don't know this.I dont say they dont do R&D at all, I just said that budget is very small, you just can see on the statistic of how small our R&D budget is. We miss many potential opportunity, including when our semiconductor expert try to get gov back up in early 1970 to develop semiconductor technology and industry and gov doesnt give any help at all.

Vision
In the 1970s, he proposed to Indonesian government and industries at the time to do research and development of microelectronic devices domestically. His proposal and dream never got realized until his death. During his life, he was never tired to dream that someday there would be chip fabrication industries built in Indonesia. He was also active in the planning of Bandung High Tech Valley (BHTV) which tries to replicate the success of California's Silicon Valley in Indonesia.

As I said, if the R&D budget is expensive, they tend dont develop it. What you have mention here doesnt need too much money to be developed and we have many clever graduates as well.
You can see UAE spend 10 billion USD only to buy missile from USA and we are reluctant to spend 2 billion USD for fighter project where the investment itself has good chance to come back after 2030
we missed it, if given the green light by the Orba govt we could at least compete with Taiwan
TSMC btw started in 1986.
