I think so. But it would be hard and I would be surprised if anyone besides Valve could pull it off.
I have a second batch steam deck and still play it often. I wish it had a slightly bigger OLED screen. I think the 16x10 8inch equivalent is a good size.
There would also need to be a fairly decent CPU and GPU upgrade. As well as either an efficiency upgrade or a bigger battery. I think with enough time if we could get a decent arm CPU with good GPU performance, but that is likely not going to happen anytime soon, this could theoretically hit all of these requirements.
I would like to see hall effect sticks and triggers by default.
That could dethrone the steam deck. Especially if it had good linux support, either steam os or bazzite would be good for me.
I don’t mind AI for coding assistance. Sometimes I am writing a function and it suggests basically what I was going to write anyways, then I just have to hit tab and move to the next section. Sometimes I use it to add comment descriptions to my functions so I don’t have to type it manually. Sometimes I use it to spitball ideas.
I think the trick is to use it as a tool to make yourself better, not to do the work for you.
