So we should ignore the Mirai sales numbers and conclude, uh, what, that the entire $40B investment is wasted and hasn't produced anything of value?

Or if we want to be charitable, surely the $40B has resulted in some advancement of the scientific knowledge. From which we can conclude that the "hydrogen economy" remains a pipe dream despite all the investment so far?

$40B is also less than a single year's worth of defense budget, of Japan, so... it's just about what's expected of a vaguely forward looking government funded program. It's not really a giant high risk make-or-break bet.
