The article essentially says 'insects have very little computers in their heads'. To me at least, this doesn't meaningfully answer the question posed in the title. Furthermore, as per my comment, the BBC article characterizes neurons as 'wires', rather than the very sophisticated low-power processors they in fact are. Wetware implementing/running efficient algorithms honed by millions of years of evolution with (probably) trillions of test cases (all the insects that have ever lived).
