Digitizing artillery is the recent trend all over the world, you're right it's not futuristic, but modern.
And practically all the 155mm/52cal being offered are digitized to a degree. If it wasn't beneficial, this wouldn't be the trend. If it makes life easier doing calculations more accurately on a computer, instead manually on a board and paper, using simpler tools, great. I think it's worth it in a scenario where time is of essence. And what do you mean by shoot and scout? Most modern towed artillery can self propel itself with out the truck. And modern artillery rounds like Excalibur also provides it to be digitzed.
All of that wasnt even the point. There are no private companies making their own designs. If it was so simple, they wouldnt have to grab tech from Europe, South Africa, or ARDE for tech absorption.
Until they actually show their own work, they need DRDO more than DRDO needs thems. Quite frankly, these PPP arrangements aren't even a bad thing.
