i can't use the term "uglier", but i think what's going on with design direction is, and has been, 3 things:
1 a person such as Jonny was able to push materials suppliers (PCB, Modem, Camera, Display, etc) to invest in tech to get lighter and more compact materials. this included innovative ways to deal with heat dissipation.
2 but the above approach has met its limitations and is pushing against the extremes of current knowhow.
3 in light of hitting upper reaches of lighter and more compact dimensions a strategic design decision had to be made to allow non-symetrical elements to be used (non flat back caused by current limitations on camera elements; weird cut-out notch in display due to under/in display sensor tech not ready yet)
thus we are in a transitional period where form is dictated by function.
i hope that for Autumn 2020 models we begin to see tech for componentry catch up to again make beautiful symmetrical designs capable.
