I think that MIRI did a mistake than decided not be evolved in actual AI research [...] MIRI was not recognised inside AI community
Being involved in actual AI research would have helped with that only if MIRI had been able to do good AI research, and would have been a net win only if MIRI had been able to do good AI research at less cost to their AI safety research than the gain from greater recognition in the AI community (and whatever other benefits doing AI research might have brought).
I think you're probably correct that MIRI would be more effective if it did AI research, but it's not at all obvious.
Maybe it should be some AI research which is relevant to safety, like small self evolving agents, or AI-agent which inspects other agents. It would also generate some profit.
There have been a couple of brief discussions of this in the Open Thread, but it seems likely to generate more so here's a place for it.
