There are a few reasons.
1. As you say the change of business model set back commercialization by a year or two and put the hockey sticks on hold.
2. Covid set the world back a year or two.
3. Then just when the green shoots of Akida 1 were beginning to show, we ploughed that back to plant Akida 2.
On the plus side:
A. Akida 2 in software simulation has been available to EAPs for a couple of years (see 3 above).
B. TeNNs is a whole new kettle of fish.
B. There is a rumour that some EAPs are moving to using Akida 2 simulation software commercially while Akida 2 silicon is finalized (Mercedes, Valeo, ...).
C. Edge Box is a powerful self-contained plug-and-play commercial/industrial system monitor demonstrating the prowess of Akida 1 which should generate some income this quarter.
D. The general AI zeitgeist.
E. The newly discovered enthusiasm for edge AI.
F. BRN's burgeoning ecosystem.
G. The pressure on the von Neumann processor makers to become truly AI-capable and save the planet.

Inbetween 2 and 3, you left out the Ukraine War, which began in February 2022 and led to the sharpest rate of interest rate rises, from May 2022, in Australia's history (14 interest rate rises to the highest in 12 years).
It was the single most depressive event, in recent history, that has had lasting consequences and couldn't be "stimulated" out of, because of all the stimulus already made, causing too much inflation.
All major economies, had these sharp interest rate rises, after years of excessive accomodative stimulation.
Covid, ended up being a boon for investments.
The Ukraine War, not so much..
This hampered new business, around the World and especially for businesses treading completely new ground.
Risk aversion was very high.
I think the biggest thing, preventing actual "sign on the bottom line" proposals now, is how fast technology and developments are happening and progressing.
The software approach hypothesis, you have with Mercedes and Valeo, gets around this, but at some stage silicon has to be a better option..
I still believe deals will be forthcoming soon.
